A ball is thrown downward with a speed of 12 ft/s from the top of a 144-foot-tall building. After t seconds, its height above the ground is given by s(t) = -24t² - 12t + 144. (a) Determine how long it takes for the ball to hit the ground. sec (b) Determine the velocity of the ball when it hits the ground. ft/sec
