A ball is thrown directly up in the air from a height of 5 feet with an initial velocity of 60 ft/s. Ignoring air resistance, how long until the ball hits the ground? Use the formula h=16t squared+60t+5, where h is the height of the ball in feet and t is the time in seconds since it is thrown. Round your answer to the nearest tenth.
A.
2.1 seconds
B.
3.8 seconds
C.
2.4 seconds
D.
1.8 seconds
