A ball A of mass M collides elastically with a similar ball B at rest as shown in figure. Initially velocity of ball A is u m/s. After collision,

A ball of mass m_(1) , collides elastically and head on with ball of mass m_(2) at rest. Then

A small ball of mass m collides elastically with a simple pendulum with bob of mass ma at rest. The macimum height attained by the bob after collision is

A heavy ball of mass 2M moving with a velocity v_(0) collides elastically head on with a cradle of three identical ball each of mass M as shown in figure. Determine the velocity of each ball after collision.

A ball of mass m moving with velocity v collides head on elastically with another identical ball moving with velocity - V. After collision

A ball of mass m moving with velocity v collides head on elastically with another identical ball moving with velocity - V. After collision

A ball of mass m is attached to the lower end of a vertical string whose upper end is fixed. An identcial ball 'B' moving with a velocity v_(0) = 6 m//s at an angle theta = 45^(@) from vertical collides elastically with the ball 'A' as shown. The verocity of the ball 'B' just after collision is
