What is the hang time of a football ball ?
When a football player punts a footbal, he hopes for a long "hang time".
A time longer than 4.5 seconds is considered good.
The height of the ball in feet after t seconds can be modeled by the following function :
H(t) =at2 +Vt+ h
Where V is the initial velocity of the ball and h the initial height of the ball.
We suppose than a punter kicks the ball with an upward velocity of 80 feet per second and his foot meets the ball 2 feet off the ground/
The height of the ball is 98 feet after 2 seconds.
1) What is the hang time of the ball ?
2) Conclude
3) How could the football player increase his "hang time " ?
Thanks for your answers
