What is the tension between the second and third cars

Reference no: EM13492081

A subway train has three cars, each weighing 1.20 x 105 N. The frictional force on each car is 103 N, and the first car, acting as an engine, exerts a horizontal force of 4.80 x 104 N on the rails.

(a) What is the acceleration of the train?

(b) What is the tension in the coupling between the first and second cars?
