Question

As you throw a ball, you exert a force on that ball of 4.2 N. You exert this force on the ball while the ball moves a distance of 0.50 m. The ball then leaves your hand and travels a horizontal distance of 8.5 m to your friend. How much work have you done on the ball?

    Answer:

    The work done is

    Wd=2.1 joule

    N/B work done is the product of force and the applied distance

    Explanation:

    We know that the work done expressed Mathematically as

    Wd =F*d

    Where Wd=work done

    F=force exerted

    d=distance within which the force was exerted

    Given from the statement

    Force =4.2N

    Distance =0.5m

    Note we did not use 8.5 m because the force was no longer in application

    Hence

    Wd=4.2*0.5

    Wd=2.1 joule
