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
