Question

d) Two bodies of masses 9kg and 15kg travelling in opposite directions on horizontal surface collide. The velocities of the 9kg and 15kg bodies before collision are 6ms-1 and 4ms-1 respectively. They separate after collision and move in the same direction in which the 15kg mass was moving before collision. Given that the velocity of 15kg body after collision is 3ms-1, find the speed of the 9kg body after impact and the percentage loss in energy
