As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 3.53 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.15 kg,determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.

A billiard ball traveling at 5.00 m/s collides with an identical billiard ball initially at rest on the level table. The initially moving billiard ball (A) deflects 60° from its original direction while the other ball, which was initially at rest, travels 30° from the original direction of A. a)Find the speed of each of the masses A and B after the collision? b) Is the collision elastic or inelastic?

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 2.8 and 8.8 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.

Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are  v1i = +34.3 cm/s  and  v2i = −20.1 cm/s,  what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f =  cm/s v2f =  cm/s

Two boxes make a perfectly elastic collision on a horizontal frictionless surface as shown in the figure. Box with mass m= 8.0 kg and speed of 4.50 m/s collides with box M. After the collision, box m recoils with a speed of 0.75 m/s. The boxes are in contact for 0.30 s. The magnitude of the average force on the 8.0 kg box, while the two blocks are in contact, is

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?
