Answer:
The work done is, w = 6 x 10² J
Explanation:
Given,
The angle of the incline, ∅ = 30°
The force applied parallel to the incline, F = 60 N
The displacement caused by the force along the incline, s = 10 m
Since the force and displacement is along the incline, the angle of incline doesn't contribute to the work done.
The work done by the force is given by the relation,
W = F · S
= 60 N x 10 m
= 600 J
Hence, the work done by Roger pushing the box is, W = 600 J
