To clean a floor, a janitor pushes on a mop handle with a force of 50.0 N.

Question:

(a) If the mop handle is at an angle of 55° above the horizontal, how much work is required to push the mop 0.50 m?

(b) If the angle the mop handle makes with the horizontal is increased to 65°, does the work done by the janitor increase, decrease, or stay the same? Explain.
