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
