A block of mass 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 the block and sticks to it. If the velocity of the bullet is 20 m/s in the horizontal
direction just before the collision then the kinetic energy just before the combined system strikes
the floor, is [Take g = 10 m/s²
. Assume there is no rotational motion and loss of energy after the
collision is negligable.]
