W=f * cos theeta *s
30 degree value =0.25
30 * 0.25 * 20
=600 * 0.25
=150.00 joule

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.
