Two particles, A and B, are moving in opposite directions along the same straight line on a smooth horizontal surface when they collide directly. The mass of A is 2m and the mass of B is 3m. Immediately after the collision, A and B are moving in opposite directions with the sam speed v. In the collision, A receives an impulse of magnitude Smv. (a) Find the coefficient of restitution between A and B. After the collision with A, particle B strikes a smooth fixed vertical wall and rebounds. The wall is perpendicular to the direction of motion of the particles. The coefficient of restitution between B and the wall is f. As a result of its collision with A and with the wall, the total kinetic energy lost by B is E. As a result of its collision with B, the kinetic energy lost by A is 2E. (b) Find the value of f.
