Answers

Answer 1

The motion is critically damped is 0.69 m.

What is meant by mass of object?

The mass of a body is the amount of matter it contains. It is a scalar value. Weight: A body's weight is the force with which the earth attracts it. It is the effect of gravity.

The property of matter that measures its resistance to acceleration in physics. The mass of an object is roughly equal to the number of atoms in it. The kilogram is the fundamental unit of mass measurement. Weight = mass multiplied by gravity's acceleration

critically damped: βω0.

x = [tex]$\left(C_1+c_2 t\right) e^{-\beta t}$[/tex] = 2 J t = 0

[tex]$\dot{x}=\left(c_1+c_2 t\right)\left(-\beta e^{-\beta b}\right)+c_2 e^{-\beta t}$[/tex] = 0 st = 0

[tex]$c_1=2 . \quad c_2=\beta \cdot 2$[/tex]

Now, [tex]$\omega_0=\sqrt{\frac{b}{m}}$[/tex]

Let the equation be mg = k . 2

so, √g/2 = √k/m = [tex]$\omega_0$[/tex]

[tex]$c_1[/tex] = 2, [tex]$c_2[/tex] = √(8/2) × 2 = 2√5

x = [tex]$(2+2 \sqrt{5} t) e^{-\sqrt{5} t}$[/tex] or [tex]$(2+2 \sqrt{3}) e^{-\sqrt{s}}$[/tex] = 0.69 m

Therefore the motion is critically damped is 0.69.

a 15 kg block slides on a horizontal, frictionless surface until it encounters a spring with a spring constant of 3600 n/m. the block comes to rest after compressing the spring a distance of 0.052 m. what is the initial speed of the block?

Answers

The initial speed of the block is 0.648 m/s

Define distance?

Distance is a quantitative or qualitative measurement of the distance between two objects or places. Distance can refer to a physical length or an estimation based on other factors in physics or common use (e.g. "two counties over"). Because spatial cognition is a rich source of conceptual metaphors in human thought, the term is also used metaphorically to mean an estimation of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance among strings of text) or a degree of separation (as exemplified by distance between people in a social network). The concept of a metric space is used to codify most such conceptions of distance, both physical and metaphorical.

Given;

mass of block, m = 15 kg

force constant k = 3600 N/m

compression , x = 0.052 m

kinetic energy = elastic potential

¹/₂mv² = ¹/₂kx²

mv²  = kx²

v=√Kx^2/m

where;

v=initial speed of the block

x=compression of the spring

a track star runs a 230 m race on a 230 m circular track in 26 s. what is his angular velocity (in rad/s) assuming a constant speed? (enter the magnitude.)

Answers

Using the concepts of angular displacement, we got that 0.241 rad/s is the angular velocity of track star which runs a 230 m race on a 230 m circular track in 26 s.

We know very well that angular velocity is given by change in angular displacement per unit time.

Here, we can see that a truck distance covered and length of circular track is same.

Perimeter of circular track is equal to the distance covered by the truck.

It means, truck rounds a full circle in 26 sec

So, the angle covered by truck is 360° or 2π radian.

Initially angle is 0 radian and final angle is 2π radian

Therefore, angular velocity =(θ[tex]_f_i_n_a_l[/tex] -θ[tex]_i_n_i_t_i_a_l[/tex])/time

                               => ω=(2π-0)/26

                               =>w=(2π/26)

                                =>w=(2×3.14)/26

                                =>ω=6.28/26

                                =>w=0.241 rad/sec.

For mass movements, gravity is the primary driving force. A trigger is frequently present in mass-wasting occurrences.

It could be caused by human operations like grading a new road, quake shaking, super volcano, storm waves, or storm-related waves. Mass-wasting is most frequently caused by an increase in water content in the slope. Rapidly dissolving snow or ice, as well as a heavy downpour, can cause the water content to rise. The force of gravity pulls everything towards to the Earth’s centre from every point on its surface. Gravity pulls downward on a level surface that is also parallel to the surface of the Earth.

Let's consider m = 1 (the mass of the cart is not changing so it is constant),

F = 2, and a = 4.

2 = 1 x 4

When doubling force we need to maintain equality so acceleration should double too. To understand it better find the ratio of force and acceleration 2/4 = 1/2. The ratio of force to acceleration should always equal half in all scenarios, this way we can see how equality is maintained.

We found that the stopping distance of a car is proportional to its kinetic energy. Energy is dissipated as heat in the brakes tires and road surface. More energy required means more stopping distance. This explains why the braking distance increases in proportion to the square of the car's speed. The kinetic energy of a car is equal to the braking force multiplied by the stopping distance.

Braking distance also depends on car speed car mass brake and tire wear and road surface. A fast heavy car with worn tires and brakes will have a longer stopping distance on wet or icy roads. Friction forces act in the opposite direction of movement, making it harder to move slowing the car down the ramp and slowing it down, thus reducing the distance covered.

what is the maximum mass that can hang without sinking from a 50.0- cm -diameter styrofoam sphere in water? assume the volume of the mass is negligible compared to that of the sphere.

Answers

One form of StyrofoamTM product, commonly used in craft projects, is Styrofoam balls. The spherical polystyrene foam objects known as Styrofoam balls range in diameter from one inch (2.54 cm) to eight inches (20.3 cm). The uses for Styrofoam balls in crafts are incredibly diverse.

Calculating the ball's volume using

V = 4/3 * pi * r3

r = 10 cm = 0.10 m.

V = 0.00418 m^3

The mass of the water with a volume of 0.0446 m3 is equal to m =??

V = 0.00418 m3,

and d = 1000 kg/m3.

m=V*dm=0.00418*1000=4.18 kg

then determining the styrofoam ball's mass.

V = 0.00418 m3

d = 32 kg per m3, which equals m = 0.00418 * 32 m = 0.1337 kg.

Finding the necessary mass to place on the ball's surface.

The distinction is what you'll need to put on the ball.

4.18 - 0.1337 = 4.046 kg ans.

75 lbs/in^2 is the value of pressure. The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.

What is pressure?

In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area.

The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure is the pressure. Pressure is expressed using a variety of units.

P1V1=P2V2

The amount of force applied to a certain region is referred to as pressure. Absolute pressure, gauge pressure, and differential pressure are the three categories into which pressure is divided.

The distance between that point and the surface, the liquid's density. Gravitational acceleration are the factors of pressure.

you see a manned aircraft in the distance while flying your drone at night. on the left, you're seeing a green light. on the right, you're seeing a red light. which direction is the aircraft headed?

Answers

The airplane is heading away from us when we see a manned aircraft in the distance while flying our drone at night.

Distance is the length between two points or items, and it is directionless. Since distance is a scalar attribute, it only takes into account the overall magnitude and ignores the start and end locations. Being a scalar attribute, distance may only be positive or zero; it cannot be the opposite.

Although kilometers (km) and centimeters (cm) or millimeters (mm) can also be used to express shorter distances, the meter (m) is the most used unit of measurement for distance (mm). When calculating distance, the letter D is usually used to denote the distance traveled.
