A person standing at the edge of a cliff throws a rock upward from a height of 220 ft above ground level with an initial velocity of 48 ft/s. Calculate the velocity of the rock when it is exactly 32 ft above the person's hand. Separate multiple answers with a comma. (Hint: Use h(t) = - 16t² + 48t + 220 as the position function, where h is in feet, t in seconds. Ignore air resistance.) Answer ft/s Keypac Keyboard Shortcu
