A batter hits a pop-up to a fielder 65 m away.?

Question

The acceleration of gravity is 9.8 m/s^2. If the ball remains in the air for 5.5 seconds, how high does it rise?

Answer 1

Height h doesn't depend on the distance x, only the vertical velocity and gravity g, or in this case flight time and g.
The time t to reach max height = total flight time/2 = 2.75 s.
h = gt^2/2 = 18.528 m
