Question
A block of mass M = 4 kg is pulled by a force F = 100 N forming an angle of 60 degrees with themhorizontal plane with friction coefficient 0.3.
Determine the work of force F, friction force and normal force.
![Solution-
Friction force (f)-
f = umg
f = 0.3 x 4 x 9. 81
f = 11.772N
Normal Force (N)-
N+ 100 sin 60 = W
N+ 100 sin 60 = mg
N+ 100 sin 60 = 4 x 9. 81
N = 125. 84 N](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fab8746ee-624c-46d0-af84-8e2840c48d96%2F9a154394-932b-4c53-bdf2-861d265568dc%2Fvoqxgi_processed.png&w=3840&q=75)
