A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.39 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude m/s direction * (with respect to the original line of motion)

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?

1. A steel ball of mass 0.5 kg is fastened to a cord 70 cm long and fixed at the far end, is released when the cord is horizontal. At the bottom of its path, the ball strikes a 2.5 kg steel block initially at rest on a horizontal surface. The collision is elastic. Find a) the speed of the ball and the speed of the block, just after the collision. b) If the block has a coefficient of kinetic friction with the horizontal surface of 0.30, how far does the block slide before coming to rest?

Two blocks of masses m, = 2.00 kg and m, = 3.70 kg are released from rest at a height of h = 5.90 m on a frictionless track as shown in the figure below.
