Particle Phas mass 1 kg and particle has mass 3 kg. They are moving in opposite directions along a smooth horizontal plane when they collide directly. Immediately before the collision Phas speed 2ums and has speed ku m s', where is a constant. As a result of the collision the direction of motion of each particle is reversed and the speed of each particle is halved. (a) Find the value of k. The magnitude of the impulse exerted in the collision is 18 Ns. (b) Find u (c) Calculate the kinetic energy lost in the collision.
