A golfer hits a golf ball off the ground with an initial vertical velocity of 176 feet per second. How long does it take for the ball to land? Use the formula h = −16t2 + v0t + h0, where h represents the height of the ball in feet, t represents the time in seconds, v0 represents the initial vertical velocity, and h0 represents the initial height. Select one:
A. 9 seconds
B. 11 seconds
C. 15 seconds
D. 18 seconds
