Homework Statement
A block moves up a 30° incline under the action of certain forces, three of which are as follows: F1 is horizontal and magnitude 40N. F2 is normal to the plane and of magnitude 20N. F3 is parallel to the plane and of magnitude 30N. Determine the work done by each force as the block moves 80cm up the incline
Homework Equations
The Attempt at a Solution
I just need to know if I'm doing the right thing here.
WF1 = 40(cos 30)(0.8) = 27.7
WF2 = 20(sin 30)(0.8) = 8
WF3 = 30(0.8) = 24
