Homework Statement
A box is dragged 16 m across a level floor by a 75N force at an angle of 35 degrees to the floor . It is then dragged by the same force 8m up a ramp inclined at an angle of 20 degrees to the floor. Determine the total work done by the force.
Homework Equations
W= F(d)Cosθ
The Attempt at a Solution
Part 1
W= (75)(16)Cos(35)
W= 982.98J
Part 2
I am not sure how to do this part, because θ is defined as being the angle between the force and the displacement. Where does the ramp fit in? Should I take the force of gravity perpendicular to the ramp (the normal force) and add that to the vertical component of my applied force?
