MRK asked:

A roofer is dragging a 15.0-kg bundle of shingles up the roof using a light rope parallel to the roof. The roof is sloped at an angle of 30.0° with the horizontal.
a.Draw a free-body diagram of the forces involved.

b.What is the force component perpendicular to the roof of the weight of the bundle of shingles?

I drew the diagram, but I really don’t understand what part b is asking me for… Do they want me to state “the perpendicular force”? do they want a value? what do they want??

THANKS!
