Question

A 100 kg car pulling a 500 kg trailer accelerates at a rate of 2 m/sec^2. If the frictional force on the trailer is 1000 N, with what force does the car pull the trailer? With what force does the trailer pull the car?

Answer 1

F^* = ma = 500[kg] * 2[m/sec²] = 1000[N] F_car - F_fr = F^*;
F_car - 1000 = 1000; Answer:
F_car = 2000[N]
