In an amusement park, two identical cars, moving with speeds of the same value, same direction and opposite directions, collide head-on and stop immediately after impact. Comparing the kinetic energy and the amount of movement of the system constituted by the two carts, before and after the collision, it is correct to state that: . a) both increased . b) the kinetic energy remained constant and the amount of movement decreased. c) both decreased. d) both remained constant. e) the kinetic energy decreased and the amount of movement remained constant
