To clean a floor, a janitor pushes on a mophandle with a force of 50.0 N. (a) If the mop handle is at an angleof 55° above the horizontal, how much work is required to pushthe mop 0.50 m? (b) If the angle the mop handle makes with thehorizontal is increased to 65°, does the work done by the janitorincrease, decrease, or stay the same? Explain.
