उत्तर

The instantaneous force which body possesses due to the combined effect of mass and velocity is called momentum of the body. Mathematically, momentum is the product of mass and velocity.
P = mv
where P represents the momentum of the body.

A smooth wedge A is fitted in a chamber hanging from a fixed ceiling near the earth's surface. A block B placed at the top of the wedge takes time T to slide down the length of the wedge. If the block is placed at the top of the wedge and the cable supporting the chamber is broken at the same instant, the block will.
