A truck with mass 2000 kg tows a boat and trailer of total mass 500 kg. The frictional coefficient for the truck is 0.080 and for the trailer is 0.050 (this is due to “rolling resistance” of the tires). The force of the truck’s drive wheels pushing backward on the pavement is 3.0 kN. (a) Determine the acceleration rate of the truck and trailer moving forward together. (b) Determine the amount of force the truck’s hitch exerts forward on the trailer.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
