Answer 1

Question#20598

A car towing a trailer accelerates up a hill. Explain about the forces between the car and a trailer.

Answer:

On a trailer acting three forces:

$F_{i}$ - the input force (force acting between the car and a trailer).

$F_{b}$ - the roll back force: $F_{b} = mgsin\alpha, \text{were } m = \text{mass}, g = \text{gravity}, \alpha = \text{the slope angle}$

$F_{f}$ - the frictional force is always in a direction opposite to the motion of the object.

If a car towing a trailer with acceleration:

The input force is more sums of forces:

$$\boldsymbol {F} _ {i} > \boldsymbol {F} _ {b} + \boldsymbol {F} _ {f}$$
