JEE Mains 03-Sep-2020 Shift 2 Solved Paper

A block of mass 1.9 kg is at rest at the edge of a table, of height 1m . 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.]
