Question

A caravan of mass 600 kg is towed by a car with an acceleration of 2 m/s2. If theresistance to motion is 300 N, what is the force exerted by the car?

Answer 1

Given data

*The given mass of the caravan is m = 600 kg

*The given acceleration is a = 2 m/s^2

*The resistance to motion is F_r = 300 N

The formula for the force exerted by the car is given as

`F=ma+F_r`

Substitute the known values in the above expression as

`\begin{gathered} F=(600)(2)+(300) \\ =1200+300 \\ =1500\text{ N} \end{gathered}`

Hence, the force exerted by the car is F = 1500 N
