A trailer with a mass of 2.00x 10^3 kg is pulled by a truck with a mass of 3.00 x 10^3 kg. If the applied force is 8750 N and the frictional force exerted by the road is 2560 N, what is the acceleration of the truck and trailer?
F = m a
m = 5*10^3 Kg
8750 - 2560 = 5*10^3 a
6.19 = 5 a
a = 1.24 m/s^2
