Explanation:
The force is 186.5 N. 3.8% of the force is directed downward. So the vertical component of the force is:
Fᵧ = 0.038 (186.5 N)
Fᵧ = 7.087 N
The horizontal component is found with Pythagorean theorem:
F² = Fₓ² + Fᵧ²
(186.5 N)² = Fₓ² + (7.087 N)²
Fₓ = 186.4 N
So the work done is:
W = Fd
W = (186.4 N) (7.4 m)
W = 1379 J
Round as needed.
