    Find the work done (in kJ) if a force of 750 N pushes a cart of mass 30 kg by 16 m.
    Question

    Find the work done (in kJ) if a force of 750 N pushes a cart of mass 30 kg by 16 m.

    A.

    24

    B.

    12

    C.

    36

    D.

    48

    Correct option is B


    The formula for work done (W) is:
    W = F × d × cos(θ)
    where:
    · F = 750 N (force applied)
    · d = 16 m (displacement)
    · θ = 0∘ (since force is applied in the direction of displacement, so cos0∘ = 1 )
    W = 750 × 16 × 1 = 12000 J = 12 kJ
