Answer on Mechanics | Relativity Question for John

Question #890
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?
Expert's answer
F* = ma = 500[kg] * 2[m/sec2] = 1000[N] Fcar - Ffr = F*;
Fcar - 1000 = 1000; Answer:
Fcar = 2000[N]

According to Newton's third law, when a first body exerts a force F1 on a second body, the second body simultaneously exerts a force F2 = −F1 on the first body. This means that F1 and F2 are equal in magnitude and opposite in direction.
So the force with which trailer pulls the car is -F<sub>car</sub>
