A baseball is batted. It's a long fly ball. 5.0 seconds later the ball reaches the outfield 100 meters away and returns to the height from which it left the bat. a. What maximum height did the baseball reach?

31 m

Explanation:

The ball is in the air for 5.0 s,

It is rising for half that time to zero vertical velocity

And falling for the same amount of time.

Distance of fall from rest is

s = ½gt²

s = ½(9.8)2.5² = 30.625 ≈ 31 m (above the batting or catching height)

whichever one it is, it's definitely not one that you included on the list you provided.
