Two toy cars can roll without friction on a horizontal surface. car a is a 5 kg. car b is 0.5 kg. both cars start from rest. equal sized forces are used to push each cart forward for a time of 1 second. after 1 second the force is removed. what is the difference in magnitude of the momenta of the two cars, right after the force is removed? choices: a. the momentum of car a(5kg) is equal to that of car b(0.5)b. the momentum of car a (5kg) is less than that car b (0.5)c. the momentum of car a (5kg) is more than that car b (0.5)d. 5.5 kg m/s
