Question

You push a stalled car with a constant force of 215 NN as it moves a distance 8.40 mm in a straight line. The amount of work that you do in this process is 1.47×103J1.47×103J. What is the angle between the direction of your push and the direction of the car’s motion?

    Answer:

    \theta=0.999^{\circ} is the angle between the displacement and the force

    Explanation:

    Given:

    Force of pushing the car, F=215\ N

    displacement of the car, s=8.4\ m

    amount of work done, W=1470\ J

    We know the formula of work:

    W=F.s\cos\theta

    where:

    • \theta= angle between the displacement and the force

    1470=215\times 8.4\times \cos\theta

    \theta=0.999^{\circ} is the angle between the displacement and the force
