The product of mass & velocity of a moving body is __________.

What name is given to the product of mass and velocity of a body ?

Name the laws involved in the following situations: (a) the sum of products of masses and velocities of two moving bodies before and after their collision remains the same. (b) a body of mass 5 kg can be accelerated more casily by a force than another body of mass 50 kg under similar conditions (c) when person A standing on roller skates pushes another person B (also standing on roller skates) and makes him move to the right side, then the person A himself gets moved to the left side by an equal distance (d) if there were no friction and no air resistance, then a moving bicycle would go on moving for ever.

if mass of body is 20kg and momentum is 40Ns then velocity of moving body is

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 moves with constant velocity of 20 ms^-1 . The mass of body is 2 kg. The unbalanced force acting on the body is _________.

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is
