Name the laws involved in the following situations: (a) the sum of products of masses and velocities of two moving bodies before and after their collision remains the same. (b) a body of mass 5 kg can be accelerated more casily by a force than another body of mass 50 kg under similar conditions (c) when person A standing on roller skates pushes another person B (also standing on roller skates) and makes him move to the right side, then the person A himself gets moved to the left side by an equal distance (d) if there were no friction and no air resistance, then a moving bicycle would go on moving for ever.
