Question

Later during that same golf outing Marc decided to show off by trying to hit the green in one shot.  He said he hit the green as the ball hung in the air for at least 15 seconds.

 

The formula for this shot is  h(x)=-16x^2+258x where h is the height of the ball and x is the number of seconds the ball is in the air.

 

1. How can Marc provide proof that his shot actually hung in the air for 15 seconds?

 

2. How long did the ball actually hang in the air? Is Marc able to mathematically back up how long he says the ball was in the air?
