Show that two equal masses undergo oblique elastic collision will move at right angles after collision , if the second body initialyy at rest .

When two spheres of equal masses undergo glancing elastic collision with one of them at rest after collision they will move

A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:

What is meant by elastic collision ? Show that when two bodies of equal masses moving in one dimension suffer elastic collision, their velocities are exchanged after collision.

Show that in one dimensional elastic collision of two particales of equal mass,the partical exchange velocities after collisions.

A moving ball of mass 0.1kg undergoes an elastic head-to-head collision with another body at rest. After collision, the first ball rebounds at one-third of its original speed while second ball starts moving forward . find the mass of the second ball.

Two balls of equal masses m each undergo oblique collision. If colision is perfectly elastic, then angle between their velocities after collision is
