12. A tee box is 48 feet above its fairway. Starting with an initial elevation of 48ft at the tee box and an initial velocity of 32 ft/s, the quadratic equation 0 =- 16t + 32t+ 48 gives the time t in seconds when a golf ball is at the height 0 feet on the fairway. a. Solve by factoring to determine how long the ball is in the air. b. What is the height of the ball at 1 second? c. What is the maximum height the ball reaches and when is it at its maximum height?
