Question: A ball is thrown vertically upward from the ground at a velocity of 64 ft per second. Its distance from the ground at t seconds

A ball is thrown vertically upward from the ground at a velocity of 64 ft per second. Its distance from the ground at t seconds is given by s(t) = -16t² + 64t.
(a) How fast is the ball moving 2 seconds after being thrown? 3 seconds after being thrown?
(b) How long after the ball is thrown does it reach its maximum height?
(c) How high will it go?
