A tee box is 128 feet above its fairway. When a golf ball is hit from the tee box with an initial vertical
velocity of 32 ft/s, the quadratic equation 0 = -16t2 + 32 + 128 gives the time t in seconds when a golf
ball is at height o feet on the fairway.
Part 1
Solve the quadratic equation by factoring to see how long the ball is in the air.
The ball is in the air a total of 4
seconds.
Part 2 out of 3
What is the height of the ball at 1 second?
One second after being hit from the tee, the ball is
feet above the fairway.
