If a cannonball is shot directly upward with a velocity of 224 ft/sec, its height, in feet, above the ground after t seconds is given by s(t)equals224 t minus 16 t squared. Find the velocity and the acceleration after t seconds. When does the cannonball reach its maximum height? What is the maximum height the cannonball reaches? When does it hit the ground?
