A bullet of mass 75g moving with velocity v strikes a of mass 50g. If bullet emerges out from bob with velocity v/3 bob just complete vertical circular motion. Find velocity v of bullet.

A bullet of mass m moving with velocity v strikes a block of mass M at rest and gets embedded into it. The kinetic energy of the composite block will be

A bullet of mass m moving with velocity v strikes a suspended wooden block of mass M . If the block rises to a height h , the initial velocity of the block will be (

A bullet of mass m is fired with velocity v in a large bulk of mass M. The final velocity v' will be

A bullet of mass 20 g moving horizontally strikes a block of mass 480 g suspended by a string of length 2 m . If the collision is completely inelastic , the minimum velocity of bullet , so that the combined mass complete vertical circle should be

A bullet of mass 20 g moving with a velocity of 500 m/s, strikes a free and goes out from the other side with a velocity of 400 m//s. Calculate the work done by the bullet in joule in passing through the tree.

A disc of mass 100 g is kept floating horizontally in air by firing bullets, each of mass 5 g with the same velocity at the same rate of 10 bullets per second. The bullets rebound with the same speed in opposite direction. Find the velocity of each bullet at the time of impact.
