Explain how to find the height at which the balls meet. Then find the height to the nearest tenth.
Set the height equations equal and solve for the time: −16t² + 56t = −16t² + 156t − 248, so t = 2.48 seconds. Substitute 2.48 into either equation to find the height, which is 40.5 feet to the nearest tenth.
Which of these steps did you include in your solution? Check all of the boxes that apply.
The balls meet at a height of ft.
40.5
