Q6. A ball A of mass 0.2 kg is moving on a frictionless surface with a speed of 3 m/s towards a ball B in rest of mass 0.1 kg. If the balls collide and velocity of the ball A is reduced to 1 m/s: (a) Find momentum of ball A before collision. (b) Find velocity of ball B after collision. (c) Show that the balls collide elastically. (d) Do they move in the same direction after collision? Why?
