The two carts of uneven mass (mass A > mass B) move on the parallel frictionless horizontal tracks. Both the carts begin from rest and encompass the similar constant force exerted on them. Until they arrive at the finish line. The force starts to exert on car A first. The force acting on cart B merely as cart A passes it. Both the carts arrive at the finish line at the same time. At the finish, cart B is moving quicker than cart A.
i) At an instant if both carts encompass the force exerted on them, is accelerating of cart A greater than, less than, or equal to the acceleration of B? Describe.
ii) Is the magnitude of cart A of final momentum greater, less than, or equivalent to the magnitude of the final momentum of cart B? Describe.
iii) Is the final kinetic energy of cart A greater than, less than, or equivalent to the final kinetic energy of cart B?
