Problem
A ball of mass 0.20kg moving at 10m s−1 collides head-on with a block of mass 0.80kg initially at rest on a smooth horizontal surface. After impact, the ball sticks to the block and they move together.
(i) Calculate their common speed immediately after the collision.
(ii) Determine the loss of kinetic energy in the collision.
