b) What is the change in kinetic energy regarding the collision?

In an elastic collision, one ball has initial velocity v when it collides head-on with another, much less massive ball, initially at rest. The velocity of the second ball after the collision is approximately equal to Multiple Choice v/2 V none of the above 2v

A 2.00-g particle moving at 5.40 m/s makes a perfectly elastic head-on collision with a resting 1.00-g object. (Assume the 2.00-g particle is moving in the positive direction before the collision. Indicate the direction with the sign of your answer.) (a) Find the velocity of each particle after the collision. 2.00-g particle 1.00-g particle m/s m/s (b) Find the velocity of each particle after the collision if the stationary particle has a mass of 10.0 g. 2.00-g particle 10.0-g particle m/s m/s (c) Find the final kinetic energy of the incident 2.00-g particle in the situations described in parts (a) and (b).

I don't understand this hw problem.

A 1500 kg car traveling eastwards at 25 m / s collides with a 2500 kg load truck going north at a speed of 20 m / s as shown in the figure. Find out the magnitude and direction of the speed of the wreck after the collision, taking into account that the vehicles had a completely inelastic collision.

In inelastic collision: a) Both linear momentum and energy are conserved.  b)  Linear momentum is conserved, but energy is not conserved.   c)  Linear momentum is not conserved, but energy is conserved.  d)  Both linear momentum and energy are not conserved.

A ball moving at 10 m/s makes an off-center elastic collision with another ball of equal mass that is initially at rest. The incoming ball is deflected at an angle of30° from its original direction of motion. Find the velocity of each ball after the collision.

An object (A) of mass 28kg is moving in a direction that makes angle of 42 degrees north of east with a speed of 5.00m/s, while object (B) of mass 16kg is moving due north with a speed of 8m/s. The two objects idea and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two objects system after the collision

A cue ball traveling at 6.57 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.   (b) Find the speed of each ball after the collision.
