Questions
A locomotive (engine) pulls a series of wagons. Which is the correct analysis of the situation?
detailed solution
Correct option is C
The force exerted by the locomotive on the wagons is equal to that exerted by the wagons on the locomotive. The locomotive moves forward because of a forward frictional force exerted by the tracks on its wheels. The backward frictional force exerted by the track on the wheels of the wagons is much smaller.Talk to our academic expert!
