Answer:
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
