Dropout · Answer 1

W = 565.42 J

Explanation:

Given that

mass, m = 20.5 kg

displacement = 5.93 m

Applied force, F = 95.3501 N

Coefficient of friction,μ = 0.389

We know that work done by force F is given as

W = F. d

d=Displacement

F=Force

W=Work

W = 95.3501 x 5.93 J

W = 565.42 J

Therefore the work done by applied force will be 565.42 J.
