    The work done on the wagon is, W = 4531 J

    Explanation:

    Given data,

    The displacement of the circus wagon, S = 23 m

    The elephant pulled with a force, Fₐ = 250 N

    The angle of direction of force with the horizontal, Ф = 38°

    Therefore, the force in the horizontal direction is,

    F = Fₐ Cos Ф

    The work done on the wagon is

    W = F · S

    = Fₐ Cos Ф · S

    = Fₐ · S · Cos Ф

    = 250 · 23 · Cos 38°

    = 4531 J

    Hence, the work done on the wagon is, W = 4531 J
