### Question

A 20 g bullet pierces through a plate of mass m1 = 1 kg and then comes to rest inside a second plate of mass n1 = 2.98 kg. It is found that the two plates, initially at rest, now move with equal velocities. The percentage loss in the initial velocity of bullet when it is between m1 and m 2. (Neglect any loss of material of the bodies, due to action of bullet. ) will be -
