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.

I would like to know if this solution is correct

 

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
