0A body of mass 20 kg moving with a velocity of 3 `m//s,` rebounds on a wall with same velocity. The impulse on the body is -

A body of mass 2 kg moving with a velocity 3 m//s collides with a body of mass 1 kg moving with a velocity of 4 m//s in opposite direction. If the collision is head on and completely inelastic, then

A body of mass 2 kg moving with a velocity 3 m//s collides with a body of mass 1 kg moving with a velocity of 4 m//s in opposite direction. If the collision is head on and completely inelastic, then

A body of mass 2 kg moving with a velocity 3 m//sec collides with a body of mass 1 kg moving with a velocity of 4 m//sec in opposite direction. If the collision is head-on perfect inelastic, then

Solve the following examples: (numerical problems) A body of mass 1 kg, moving with a velocity of 4 m/s collides with a body of mass 0.5 kg moving with a velocity of 2 m/s . If the velocity of the first body after collision is 8/3 m/s , find the velocity of the second body after collision.

A body of mass 2 kg is moving with velocity 10 m / s towards east. Another body of same mass and same velocity moving towards north collides with former and coalsces and moves towards northeast. Its velocity is

A body of mass 20 kg is moving with a velocity of 2v and another body of mass 10 kg is moving with velocity V along same direction. The velocity of their centre of mass is

A body of mass (1)/(4) kg moving with velocity 12 m//s is stopped by applying a force of 0.6 N. Then impulse is :-

A body of mass (1)/(4) kg moving with velocity 12 m//s is stopped by applying a force of 0.6 N. Then impulse is :-

A body of mass 2 kg moving with a velocity of 3 m/sec collides head on with a body of mass 1 kg moving in opposite direction with a velocity of 4 m/sec. After collision, two bodies stick together and move with a common velocity which in m/sec is equal to
