Suppose a player hits several baseballs. Which baseball will be in the air for the longest time?

A

The one with the farthest range.

B

The one which reaches maximum height.

C

The one with the greatest initial velocity.

D

The one leaving the bat at $45^o$ with respect to the ground.

Solution

Time of flight $=2 \cdot \sqrt{\frac{2 h}{g}}$

$\therefore T \propto \sqrt{h}$

Hence the one which reaches maximum height flies for longer time.
