15-75. The 0.5-kg ball is fired from the tube at A with a velocity of v = 6 m/s. If the coefficient of restitution between the ball and the surface is e = 0.8, determine the height h after it bounces off the surface. v = 6 m/s 130°

The two flat cars A and B each have a mass of 80kg. If the man C has a mass of 70kg and jumps from A with a horizontal relative velocity of vC/A= 2 m/s and lands on B, determine the velocity of each car after the jump. Neglect the effect of rolling resistance.

t Collar A (30 kg) and collar 8 (18 kg) slide along the smooth rod with the given velocities when they collide with each other. If the coefficient of restitution between the two collars is e0.75, determine the velocities of collar A and collar 8 after the collision using conservation of momentum and the coefficient of restitution. 5 m/s 10 m/s

Each ball has a mass m and the coefficient of restitution between the balls is e. If they are moving towards one another with a velocity v, determine their common velocity when they reach the state of maximum deformation. Neglect the size of each ball. Note: it may seem like you don't have enough information to solve this, but you do. Work it out using the variables e and v. Give your answer in metres per second (m/s)/ V B
