which type of spring do you choose to most closely reach the targeted launch speed of 12.6 m/s? Show your work and explain your answer using what you know of kinetic energy, elastic potential energy, and conservation of energy.
A linear spring with a spring constant of 77.2 N/m would be the best choice to most closely reach the targeted launch speed of 12.6 m/s.
Which kind of spring should you use to launch a rocket at 12.6 m/s, your intended launch speed?The type of spring that would most closely reach the targeted launch speed of 12.6 m/s is a linear spring. This is because a linear spring is able to convert stored potential energy into kinetic energy most efficiently. This process relies on the conservation of energy, which states that energy can neither be created nor destroyed, only converted from one form to another. In the case of a linear spring, the elastic potential energy stored in the spring is converted into kinetic energy as the spring compresses and then launches the object.To calculate the spring constant needed to reach the target launch speed, we must first determine the elastic potential energy stored in the spring. This is equal to the spring constant multiplied by the square of the displacement of the spring (E = 1/2 kx^2). We then use this value to calculate the kinetic energy of the object at launch (KE = 1/2 mv^2). Finally, we can use the conservation of energy to solve for the spring constant (k = 2(KE)/x^2). In this case, the mass of the object is 1 kg. The target launch speed is 12.6m/s. Plugging these values into the equation above, we can calculate the spring constant needed to reach the target launch speed:k = 2(1/2 (1) (12.6^2)) / (1^2)k = 77.2 N/mTherefore, a linear spring with a spring constant of 77.2 N/m would be the best choice to most closely reach the targeted launch speed of 12.6 m/s.To learn more about conservation of energy refer to:

diameter of a tire is 58.8 cm.
Find the number of revolutions the tire
makes during this motion, assuming no slip-
ping.
Answer in units of rev.
The answer is Number of revolutions = 31.95 rev.
How to find the Number of Revolutions?"Revolutions Per Minute" (or "RPM") means how many complete turns occur every minute.
To find the total number of revolutions, divide the total distance by distance covered in one revolution.
Given ,
Initial speed, u = 0m/s
Final speed, v = 9.9m/s
Time, t =12.7.4secs
Diameter = 58.8cm to meters = 58.8/100 = 0.588m
To find the acceleration;
Acceleration, a = (v - u)/t
Acceleration, a = (9.9 - 0)/12.7
Acceleration, a = 9.9/12.7
Acceleration, a = 0.77m/s²
Now find the distance covered by the tire using the second equation of motion.
S = ut + ½at²
S = 0(12.7) + ½*0.77*12.7²
S = 0 + 0.435*129.96
S = 62.09m
The circumference of the tire is,
Circumference = 3.142 * diameter
Circumference = 3.142 * 0.588
Circumference = 1.84m

45 days.
Counts/s
The activity is a radioactive material is the number of counts per second it produces. 1 count per second (cps) = 1 Becquerel (Bq).
What is radioactive?As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration. During the first half of the twentieth century, much of modern physics was devoted to exploring why this happens, with the result that nuclear decay was fairly well understood by 1960. Too many neutrons in a nucleus lead it to emit a negative beta particle, which changes one of the neutrons into a proton. Too many protons in a nucleus lead it to emit a positron (positively charged electron), changing a proton into a neutron. Too much energy leads a nucleus to emit a gamma ray, which discards great energy without changing any of the particles in the nucleus. Too much mass leads a nucleus to emit an alpha particle, discarding four heavy particles (two protons and two neutrons).To learn more about neutrons refer to:

Collision, in physics, is the action of two or more objects coming into contact with each other. The result of this contact can be anything from a minor stop-and-go jolt to a catastrophic impact that destroys both objects involved. Collisions can occur between two-dimensional objects, such as billiard balls, or between three-dimensional objects, such as cars. A collision can be elastic, in which the objects rebound from each other, or inelastic, in which the objects stick together. The collision can also be perfectly inelastic, in which the objects stick together and move as a single object after the collision. In all cases, the momentum of the objects before the collision is equal to the momentum of the objects after the collision.

How can I calculate the speed of an object?The equation for uniformly accelerated motion, which states that an object's final velocity, v, is equal to its beginning velocity, u, plus the product of its acceleration, a, and the time taken, t, serves as the theoretical foundation
As v = u + at, this formula can be used.
Following are the procedures to determine a particle's velocity:
Use the equation v = u + at in step one, where v is the end velocity, u is the beginning velocity, an is the acceleration, and t is the duration.
Substitute the values into the formula in step 2 to complete. Here, u = 0 (since the particle is initially at rest),
a = 6 m/s2 and t = 8 s
v = 0 + (6 m/s2) × (8 s) (8 s)
v = 48 m/s

24 hours/day
It will take our ship 3 year to travel from Earth to Mars if the speed is 3,050 km/hr.
What is speed?The distance travelled per unit of time is most commonly known as speed. It describes how quickly an object moves. The magnitude of the velocity vector is represented by speed, which is a scalar quantity. It's aimless. A faster moving object has a higher speed. It is moving slower if it has a lower speed. It has no speed if it is not moving at all.
The following formula is used to calculate the constant velocity of an object moving in a straight line:
S = d / t
Distance from Earth to Mars = Distance from Mars to Sun - Distance from Earth to Sun
Distance from Earth to Mars = 230,000,000 km - 150,000,000 km
= 2.3 × 10⁸ - 1.5 × 10⁸
= (2.3-1.5) × 10⁸

= 8 × 10⁷ km
Time = Distance ÷ Speed
Given speed = 3,050 km/hr
Distance = 8 × 10⁷ km
Putting the values,
Time = 80,000,000 ÷ 3,050
Time = 26229.51

Callisto completes one (circular) orbit of Jupiter in 16.7 days. The distance from Jupiter to Callisto is 1.88×10^9m. What is the centripetal acceleration of Callisto?
The centripetal acceleration of Callisto is 3.56 m/s².
What is centripetal acceleration?Centripetal acceleration is a characteristic of an object's motion along a circular path. Centripetal acceleration applies to any item travelling in a circle with an acceleration vector pointing in the direction of the circle's center.
Angular velocity of Callisto = (2π) ÷ (16.7 × 24 × 60 × 60)
= 4.3546 × 10⁻⁶rad/s
The distance from Jupiter to Callisto is 1.88×10⁹ m.
Hence, the centripetal acceleration of Callisto is = ω²r
= ( 4.3546 × 10⁻⁶)²× 1.88×10⁹ m/s²
= 3.56 m/s²

7) A battery of emf 8 Volt and internal resistance 2 Ohm is connected to a straight wire of length 20cm, cross-sectional area 3x108m² and its resistivity 4.5×10 2.m. The magnetic flux density at a point which lies at normal distance of 10cm away from the axis of the wire is:
The square solenoid has sides of 25 cm and 100 wire turns. The resistance is set to 10 ohms.
Define magnetic flux density ?
The magnetic flux density, also known as magnetic induction, is the number of force lines that pass through a unit area of material, B. The tesla is the magnetic induction unit (T).
Magnetic flux is basically the total magnetic field that passes through an area. It is a useful tool for describing the effects of magnetic force on something in a specific area. Magnetic flux measurement is specific to the area chosen.
Magnetic Flux Density is the amount of magnetic flux passing through a unit area perpendicular to the direction of the magnetic flux. By B=H, Flux Density (B) is related to Magnetic Field (H). It is expressed in Webers per square metre, which is equivalent to Teslas [T].
