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:

In a perfectly elastic collision between two objects, which of the following is true?

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 body of mass M𝑀 moving with a speed u𝑢 has a head-on elastic collision with a body of mass m𝑚 originally at rest. If M>>m𝑀>>𝑚, the speed of the body of mass m𝑚 after collision will be nearlyAumM

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?
