Question

A man pulls a trolley through a distance of 20m on a smooth horizontal surface . The handle of the trolley make an angle of 30 degree with the horizontal surface . If there force applied By the man 30N, calculate the work done in the pulling the trolley?

Answer 1

W=f * cos theeta *s

30 degree value =0.25

30 * 0.25 * 20

=600 * 0.25

=150.00 joule

Answer 2

Hey dear,

● Answer -
W = 520 J

● Explaination -
# Given -
F = 30 N
s = 20 m
θ = 30°

# Solution -
Work done in pulling the trollley -
W = F.s = Fscosθ
W = 30 × 20 × cos30°
W = 600 × 0.866
W = 520 J

Therefore, work done in moving the trolley is 520 J.

Hope this helps you.
