Suppose a stone is thrown vertically upward with an initial velocity of 48 ft/s from a bridge 64 f above a river. By Newton's laws of motion, the position of the stone (measured as the height abov the river) after t seconds is s(t) = –16t² + 48t + 64, where s = 0 is the level of the river. a). Find the velocity and acceleration functions. b). What is the highest point above the river reached by the stone? c). With what velocity will the stone strike the river?
