Rain falls vertically down 4m/s. A merry-go-round goes in a horizontal circle with constant speed 6m/s. At what angle to the vertical should a person in the merry-go-round hold an umbrella to get maximum protection from rain? Is this a constant angle?

Since the speed of both remains the same, the man should hold the umbrella at same angle with respect to himself.
