Question

A train consists of a 4300-kg locomotive pulling two loaded boxcars. The first boxcar has a mass of 12,700 kg and the second 16,300 kg. Presume that the boxcar wheels roll without friction and ignore aerodynamics. The acceleration of the train is 0.559 m/s2

(a) With what force, in Newtons, do the boxcars pull on each other?

(b) With what force (N) do the locomotive and first boxcar pull on each other?

(c) With what force (N) must the tracks push on the locomotive?

Answer 1

Concept: here we use Newton’s law of motion to find out different forces
