a 3 kg sphere moving at 30 m/s makes a perfectly inelastic collision with a second sphere of 6 kg that is at rest. (a) what is the velocity of the spheres after the collision? (b) how much kinetic energy is lost in the collision?

Answers

The energy an object has as a result of motion is known as kinetic energy.A force must be applied to an object in order to accelerate

How much kinetic energy is lost in the collision?

Given,

m1 = 3 kg

Mass, = 3kg

Speed, = 30 m/s

u2= 0

= 1 kg

Speed after collision = 6 m/s

Kinetic energy lost, K×E = ?

During collision, momentum is conserved.

Before collision, the kinetic energy is

KE =1/2(3)*(3)*(30)+1/2*1*(0)²

KE=1/2*4*25+0

By plugging in the values we get,

K×E = 50 J

Therefore, kinetic energy before collision is 50 J

Kinetic energy after collision:

KE =1/2(4+1)+KE

KE = 40J+KE

Since,

Initial Kinetic energy = Final kinetic energy

50J=40J+K*E

50 J = 40 J + K×E(lost)

K×E(lost) = 50 J - 40 J

F = frictional force

a = μmg / m

a = μg

a = 0.168 x 9.8

a = 1.64m/s²

To calculate the speed of sled we use:

v² = u² - 2as

v² = (4.53)² - 2x 1.64 x 3.58

v² =  8.7785

An inelastic collision is a collision in which there is no internet loss in kinetic energy within the gadget because of the collision. each momentum and kinetic electricity are conserved portions in elastic collisions.

Calculation:-

50 mph = (50 × 0.477)

    = 22.35

   Applying the law of conservation of momentum.

we get the:-

m₁u₁ + m₂u₂ = (m₁ + m₂)V

V = m₁u₁ + m₂u₂/(m₁ + m₂)

   = 4000 × 22.35 + 1000 × (-22.35) / 4000 +1000

V = 13.41 m/s

 = 13.41/0.447

= 30 mph

Hence, the common speed of the car is 30mpH.

An inelastic collision is a come between two bodies in which the full kinetic energy of the two bodies remains equal. In an ideal, perfectly elastic collision, there may be no internet conversion of kinetic strength into other kinds which includes heat, noise, or capacity electricity.

Elastic collisions arise whilst both the momentum and kinetic energy are conserved, just like how billiard balls bounce off each different and move at the same speeds as earlier. Inelastic collisions appear whilst simplest the momentum is conserved but not the kinetic power.

The weight of box 2 and box 3 is 33.72N and 15.32N

According to Lami's Theorem, if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two forces. The magnitudes of concurrent, coplanar, and non-collinear forces that keep an object in static equilibrium are all related to Lami's Theorem. This theorem also aids in the analysis of most mechanical and structural systems. For all three forces used in Lami's Theorem, the proportionality constant is the same.

Given box1 weighs 31N

Given two angles 63 and 24

So the third angle will be

180 – 87

= 93

By using Lamis theorem

T_2/(SIN 93)=T_3/(SIN (90+63))=T_1/(SIN (90+24))

Here T1 = 31N

Weight of box 2 = w2 = 31/cos24 x sin 93

if more massive stars have more hydrogen in their cores than less massive stars, why do they have shorter lifetimes?

Answers

Thermonuclear fusion occurs faster in massive stars so larger stars use up all their fuel in less time.

The more mass a star has the faster it will exhaust its fuel supply and the shorter its lifespan. The most massive stars could burn up and explode in a supernova after just a few million years of nuclear fusion. Massive stars are the largest, hottest, and brightest main-sequence stars and are blue, blue-white, or white in color.

Massive stars run out of hydrogen fuel very quickly and therefore have short lives. This is because the more massive the star the greater the fuel consumption. Even if a high-mass star has more fuel it uses it up very quickly so it does not live as long as a low-mass star. A main-sequence star's mass determines the fundamental properties of its luminosity surface temperature radius and lifetime.

An 0.8 kg cart rolls down a frictionless hill of height 0.32m. At the bottom of the holl the cart rolls on a flat surface., which exerts a frictional force if 2 n on the cart. How far does the cart roll on the flat surface before it comes to a stop

Answers

The distance travelled by the cart  on the flat surface before it comes to a stop is 1.25 m.

What is the acceleration of the cart?

The acceleration of the cart is determined by applying Newton's second law of motion as shown  below.

F  = ma

a = F/m

a = 2 N / 0.8 kg

a = 2.5 m/s²

The velocity of the cart at the bottom of the hill is calculated as;

u  = √2gh

u = √(2 x 9.8 x 0.32)

u = 2.5 m/s

The distance travelled by the cart before stopping;

v² = u² - 2as

where;

v is the final velocity of the cart = 0u is the initial velocity = 2.5 m/sa is the accelerations is the distance travelled

2as  = u²

s = u²/2a

s = (2.5²) / (2 x 2.5)

s = 1.25 m

If a roller coaster car increased its mass to twice its original value, then by what factor would its kinetic energy change? the roller coaster car's kinetic energy would?

Answers

The object's kinetic energy is proportional to its mass.

By doubling the mass kinetic energy the roller coaster car's kinetic energy is also doubled.

What is meant by kinetic energy?

In physics, an object's kinetic energy is the energy it has as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a given velocity. Unless the body's speed changes, it retains its kinetic energy after gaining it during acceleration. The body does the same amount of work when slowing down from its current speed to rest. Formally, kinetic energy is any term in a system's Lagrangian that includes a time derivative.

Gottfried Leibniz and Johann Bernoulli established the principle in classical mechanics that by describing kinetic energy as the living force, vis viva. The Netherlands' Willem's Gravesande provided experimental evidence of this relationship.

all of the following statements are correct except group of answer choices resistance tests may not reflect the actual performance conditions of an ignition coil. current ramping can be used to test for current limits and charging rise time of the ignition circuit. testing an ignition coil for resistance will always indicate its condition. a digital storage oscilloscope is used to perform current ramping tests.

Answers

Given statements are correct according to ignition coil resistance.

Resistance testing could not accurately represent how an ignition coil performs in practice. Testing the current limits and charging rise time of the ignition circuit can be done using current ramping. A coil's state may always be determined by measuring the resistance of the coil. Testing of current ramping is done using a digital storage oscilloscope.

What is ignition coil resistance?

Although most ignition coils' primary resistance should range from 0.4 to 2 ohms, you should check the manufacturer's specifications for the exact value. If the reading is zero, the ignition coil needs to be changed since the primary windings have internally shorted.

The resistance of an ignition coil can always be used to assess its condition.

The actual operating conditions of an ignition coil might not be captured by a resistance test.

Current ramping can be used to test the current limitations and charging rise time of the ignition circuit.

A digital storage oscilloscope is used for the ramping tests that are currently being done.
