Question

During a baseball game a batter hits a long flyball. If the ball remains in the air for 6.0 sec, how high does it rise?

Answer 1

When the ball is at its high point, it has zero velocity for an instant and falls for half the time it was in the air, the distance it falls is:

H = 0.5g(T/2)² = 0.5(9.8m/s²)(6/2s)² = 44.1 m.
