Question

During a physics experiment, a class drops a golf

ball off a bridge toward pavement below. The
bridge is 75 ft high. The function h = -16t2 + 75
gives the golf ball's height h in feet above the
pavement after t seconds. Use the graph of the
function at the right. After how many seconds
does the golf ball hit the pavement?

Answer 1

I did the math and the answer of your question is 2.17 seconds.
