A bullet has a mass of 20 g and is moving with a speed of `1000 cms^(-1)`. It can penetrate 10 cm of a given target before coming to rest. If the same target were only 6 cm thick, what will be the speed of the bullet when it comes out ?

A bullet of mass 0.02 kg is moving with a speed of 10 ms^(-1). It can penetrate 10 em of wooden block, and comes to rest. If the thickness of the target would be 6 cm only find the KE of the bullet when it comes out

A bullet of mass 30 g moving with a speed of 500 ms^(-1) pentrates 10 cm into a fixed target. Calculate the average force exerted by target on the bullet.

A bullet of mass 10 gm moving with a velocity .u. penetrates 4 cm in to a target before coming to rest. If the average resistance offered by the target is 200 N, the value of .u. is
