Answer to Question #219772 in Physics for Aliyu

Question

A tractor of mass 2000kg pulls a trailer of mass 1500kg. The total frictional force is 3000N and acceleration of tractor and trailer is 3ms^-2 calculate:
a. The force exerted on the tractor by the tow bar when acceleration is 3ms^-2
b. The force exerted when did tractor and the trailer are moving on a constant speed of 4ms^-1

Answer 1

$$F=(2000+1500)3+3000=13500\ N$$

$$F'=3000\ N$$
