Billiard ball A of mass 5 kg. Moving with speed 6 m/s collides head-on with ball B of equal mass. What are the speed of the two balls after the collision, assuming it is elastic? Assume both balls are moving initially with ball B traveling 2.5 m/s along the same direction as A.

Two particles with masses 2m and 8m are moving toward each other along the x axis with the same initial speeds vi. Particle 2m is traveling to the left, while particle 8m is traveling to the right. They undergo an elastic, glancing collision such that particle 2m is moving in the negative y direction after the collision at a right angle from its initial direction. (a) Find the final speeds of the two particles in terms of vi.

A 10.0-g marble slides to the left with a velocity of magnitude 0.400 m/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head-on, elastic collision with a larger 30.0-g marble sliding to the right with a velocity of magnitude 0.200 m/s. Find the velocity of each marble (magnitude and direction) after the collision. (Since the collision is head-on, all the motion is along a line.) (b) Calculate the change in momentum (that is, the momentum after the collision minus the momentum before the collision) for each marble.

You are at the controls of a particle accelerator, sending a beam of 2.70×107 m/s protons (mass m ) at a gas target of an unknown element. Your detector tells you that some protons bounce straight back after a collision with one of the nuclei of the unknown element. All such protons rebound with a speed of 2.40×107 m/s . Assume that the initial speed of the target nucleus is negligible and the collision is elastic. What is the speed of the unknown nucleus immediately after such a collision?

A 102 kg running back is traveling in the positive direction at 12 m/s when a 109 kg linebacker traveling at 10 m/s in the negative direction tackles the running back. Assuming a perfectly plastic (inelastic) collision, what is their post-collision velocity?

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?

A 0.060 kg ball, initially moving at a speed of 10.0 m/s, is struck by a bat causing it to rebound in the opposite direction at a speed of 15.0 m/s. Calculate the magnitude of the impulse on the ball in the collision. Recall the impulse-momentum theorem.

Two ice skaters with masses of 22.8 kg and 11.1 kg slide toward each other on a frictionless surface with speeds of 3.6 m/s and 2.8 m/s respectively. The two ice skaters lock hands after colliding head-on. Find the final speed of the two ice skaters.

Car A and Car B are traveling in the same direction (call it ), with B behind A, and initial speeds vA=5.6 m/s, and vB = 6 m/s. The cars have identical mass m=103 kg, and they experience an elastic collision. Now, this collision is observed by a third person traveling in a car with constant velocity v=6 m/s, traveling in the same direction as the two cars. From the point of view of this person calculate the following: Find the initial momentum of car a and b Find the final momentum of car a and b Find the total kinetic energy

A 5.3 kg sphere makes a perfectly inelastic collision with a second sphere initially at rest (they stick together after the collision). The composite system moves with a speed equal to one third the original speed of the 5.3 kg sphere. What is the mass of the second sphere?
