Ball in Air Quadratics

A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
 h = -16t² + 64t + 960.
When did the ball hit the ground?

• 10 seconds

• 2 seconds

• 5 seconds

• 7 seconds

The graph below describes a ball that was kicked. Which of the following is a true statement describing the graph?

• The ball was kicked from 500 centimeters from the ground and it traveled for 4 seconds.

• The ball was kicked from the ground and it was in the air for 4 seconds.

• The ball had a maximum height of 2000 centimeters and it was in the air for a total of 2 seconds.

• The ball had a maximum height of 1000 centimeters and it was in the air for 4 seconds.

If a ball if thrown into the air is represented by the function
h(t) = -16t²+80t, where t represents the time in seconds and h(t) is the height of the ball in feet. Find the time it will take to reach its maximum height. 

• 8 mins

• 2.5 seconds

• 5 seconds

• 604 seconds
