Question

Two particles approach each other with equal and opposite speed, v . The mass of one particle is m , and the mass of the other particle is n m , where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown. Elasic collision in three stages. Before the collision, a ball of mass m moves to right at speed v and a ball of mass n times m moves to the left along the same line at speed v. During the collision, both balls are instantaneously at rest. After the collision, the left ball rebounds with velocity V subscript m final to the left. The velocity of right ball after the collision is denoted v subscript n times m final, and its direction is unknown. After the collision, the first particle moves in the exact opposite direction with speed 2.95 v , and the speed of the second particle, v n m , final , is unknown. What is the value of n ? n =
