A mass `m_(1)` moves with a great velocity. It strikes another mass `m_(2)` at rest in head-on collision. It comes back along its path with low speed after collision. Then

A particle of mass m_(1) moving on a smooth surface with some velocity strikes another particle of mass m_(2) at rest. The head - on elastic collision takes place. After the collision , particles move with equal speed in opposite direction . Determine the mass ratio.

The sphere A of mass m_(1) moves with velocity V on a frictionless horizontal surface and strikes with sphere B of mass m_(2) at rest. The sphere A comes back with speed V//10 . Choose the correct option.

A billiard ball of mass M , moving with velocity v_1 collides with another ball of the same mass but at rest . If the collision is elastic , the angle of divergence after the collision is

A ball of mass m moving with velocity u strikes another identical ball at rest. Find the velocities of the balls after the collision if the coefficient of restitution is e and the collision is head -on. Also , calculate the loss in K.E.

Body A of mass 4m moving with speed u collides with another body B of mass 2m at rest the collision is head on and elastic in nature. After the collision the fraction of energy lost by colliding body A is :

Body A of mass 4m moving with speed u collides with another body B of mass 2m at rest the collision is head on and elastic in nature. After the collision the fraction of energy lost by colliding body A is :
