Explain how to find the height at which the balls meet. Then find the height to the nearest tenth.
Answer:
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.
