A block of mass of 1.9 kg is at rest ...

A block of mass of 1.9 kg is at rest at the edge of a table , of height 1 m . A bullet of mass 0.1 kg collides with block and sticks to it. If the velocity of the bullted is 20 m/ s in the hoizontal direction just befor the combined system strikes the florr , is [ Take ` g = 10 m//s^(2)` . Assume there is no rotational motion and loss of energy after the collision is negligble.
