1. The problem statement, all variables and given/known data
A punter kicks a football to the same height but at various velocities and angles. Which of the three punts has the longest hang time?
The illustration shows three trajectories: A, B, and C. In order for range from smallest to largest is: A, B, C.


2. Relevant equations
h = Voy^2/(2*g)


3. The attempt at a solution
Since the height of the projectile does not take into consideration the time of the projectile all three would have the same hang time.

Just wondering if this is correct.

Thank you,
TS

Yep. Good job.
