Recall swinging on a swingset as a kid. Assuming the chains or ropes for the swing were kept taut, the seat of the swing traced a circular arc. Now suppose you're on a swing hanging from ropes which are 6 ft long such that the seat is positioned 2 ft above the ground at rest. You swing forth to a terminal position /4 radians from your initial position at rest on the swing. At the height of your swing forth how high are you off the ground?
