    Answer:

    6544.07 J

    Explanation:

    From the question given above, the following data were obtained:

    Distance (d) = 15 m

    Force (F) = 628 N

    Angle (θ) = 46°

    Workdone (Wd) =?

    The work done can be obtained by using the following formula:

    Wd = Fd × Cos θ

    Wd = 628 × 15 × Cos 46

    Wd = 9420 × 0.6947

    Wd = 6544.07 J

    Therefore, the workdone is 6544.07 J
