A ball is thrown vertically upward with an initial velocity of 48 feet per second. If the ball started its flight at a height of 8 feet, then its height s at time t can be determined by: s(t)=-16t squared +48t+8. Where s(t) is measured in feet above the ground and t is the number of seconds of flight. Determine the time it takes for the ball to attain its maximum height. What would be the maximum height of the ball and how long will it take for the ball to hit the ground?
