Question: Cable exerts a constant upward tension of magnitude 1.94×10^4N on a 1.80×10^3 kg elevator as it…

a) Find the work done by the tension force on the elevator (in J).

b) Find the work done by the force of gravity on the elevator (in J).

I know I have to apply the equation for the work done by a constant force during a linear displacement, W = (Fcos(theta))d.
Where do I get the value of cos theta?
