last time i needed some calc help now i got a physics question

22. [CJ6 3.P.061.]
The punter on a football team tries to kick a football so that it stays in the air for a long "hang time." If the ball is kicked with an initial velocity of 23.4 m/s at an angle of 60.0

 

nvm i figured it out

Vfy=Viy+at
and Vfy=-Viy

 

Long enough to kill the returner.

What's the hang time?

The same amount time it takes for a train that leaves St. Louis to get to Chicago traveling at 78mph.

it was suppose to be assumed it had a 0 verticle displacement so i figured it out
