A disc of mass `10 g` is kept floating horizontally by throwing `10"marbles"//"second"` against it from below.If the mass of each marble is `5 g` , the velocity with which marbles are striking the disc (the marbles strike the disc normally and rebound downward with the same speed)

A disc of mass 10 g is kept floating horizontally by throwing 10 marbles per second against it from below . If mass of each marble is 5 g Calculate the velocity with which marbles are striking the disc . Assume that marbles strike the disc . Normally and rebound downwards with the same speed.

A dise of mass 10 g is kept floating horizontally by throwing 10 marbles per secound against it from below . If mass of each marble is 5 g Calculate the velocity with which marbles are striking the disc . Assume that marbles strike the disc . Normally and rebound downwards with the same speed.

A disc of mass 10 gm is kept horizontally in air by firing bullets of mass 5 g each at the rate of 10//s. If the bullets rebound with same speed. The velocity with which the bullets are fired is -

A disc of mass 5 kg is kept floating horizontally in mid air by firing 10 bullets per second vertically up. If the mass of each bullet is 50 gm and bullets rebound with same speed, the speed of each bullet is, (g = 10 ms^(-2) )

A disc of mass 5 kg is kept floating horizontally in mid air by firing 10 bullets per second vertically up. If the mass of each bullet is 50 gm and bullets rebound with same speed, the speed of each bullet is, (g = 10 ms^(-2) )

A disc of mass 0.5kg is kept floating horizontally in mid air by firing bullets of mass 5 g each, vertically at it at the rate of 10 per second. If the bullets drop dead. The speed of the bullet striking the disc is (g=10 ms^(-2) )
