Problem
Two blocks on a smooth horizontal surface collide and stick together. The first block of mass 4kg moves to the right at 8m s−1, while the second block of mass 2kg moves to the left at 4m s−1.
(i) Determine their common speed just after the collision.
(ii) Calculate the percentage loss of kinetic energy in the collision (answer correct to one decimal place).
