Question

14. A locomotive (engine) pulls a series of wagons. Which is
the correct analysis of the situation?
(a) The train moves forward because the locomotive
pulls forward slightly harder on the wagons than the
wagons pull backward on the locomotive.
(b) Because action always equals reaction,
locomotive cannot pull the wagons. The wagons
pull backward just as hard as the locomotive pulls
forward, there is no motion.
The locomotive's force on the wagons is as strong
as the force of the wagons on the locomotive, but
the frictional force on the locomotive is forward
and large while the backward frictional force on the
wagons is small.
(d) The locomotive can pull the wagons forward only if
it weighs more than the wagons.
