## Question:

A 500 kg trailer being pulled behind a car is subject to a 100 Newton resistance force due to friction. What force must the car exert on the trailer if the trailer is to move a) at a constant speed of 25 km/hr? b) forward with an acceleration of 2.0 m/s{eq}^2 {/eq} c) starting from rest (a=k), the car and trailer travel 150 m in 10 s?

## Equilibrium Of Forces:

In the Equilibrium condition of the force, the net force acting on the system becomes zero and the object remains in the rest condition. In the equilibrium condition the sum of the horizontal and the vertical forces become equal to zero.

Given

Mass of the trailer is {eq}m= 500\ kg {/eq}

Resistance force due to friction is {eq}F_r= 100\ N {/eq}

Constant speed of the trailer is...
