Answer to Question #5516 in Mechanics | Relativity for Sam
m = 100 kg
M = 500 kg
a = 2 m/s^2
Fr = 1000N
Accordingly to the trird Newton's law, the trailer pull the car with the same force as the car pull the trailer. Now let's use the second Newton's law:
m*a = M*a + Fr.
100*2 = 500*2 + 1000, but 200 <> 2000.
We see that the second Newton's law is failed. The problem has impossible conditions.
