A perfectly elastic ball `P_(1)` of mass 'm' moving with velocity `v` collides elastically with three exactly similar balls `P_(2), P_(3), P_(4)` lying smooth table. Velocity of the four balls after collision are
.

A ball of mass m moving with velocity v collides elastically with another ball of identical mass coming from the opposite direction with velocity 2v. Their velocities after collisions are-

A ball of mass M moving with a velocity v collides perfectly inelastically with another ball of same mass but moving with a velocity v in the opposite direction. 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_(1) is moving with velocity 3v. It collides head on elastically with a stationary ball of mass m_(2) . The velocity of both the balls become v after collision. Then the value of the ratio (m_(2))/( m_(1)) is

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 truck moving on horizontal road east with velocity 20ms^(–1) collides elastically with a light ball moving with velocity 25ms^(–1) along west. The velocity of the ball just after collision
