Two identical balls A and B collide head on elastically. If velocities of A and B, before the collision are +0.5m/s and -0.3m/s respectively, then their velocities, after the collision, are respectively:

A ball A collides head-on with another ballB of equal mass. Assuming that ball B is atrest and their collision is elastic, determinethe final velocities of these balls

Two practically elastic spheres collide. If their velocities before impact have same magnitude and opposite directions and one has a mass 3 times the other, what are their velocities after impact?

If two balls of different masses and velocities collide head on, which statements correctly describe their collision?Multiple select question.The impulses imparted on them will be equal in magnitude and direction.The forces that they exert on each other will be equal in magnitude and direction.The impulses imparted on them will be equal in magnitude, but opposite in direction.The forces that they exert on each other will be equal in magnitude, but opposite in direction.

A 0.280-kg ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with one-fourth the original speed of the first ball. The mass of the second ball is
