A projectile is launched with an initial velocity of 117feet per second from the height of2 feet. The functionmodels the path of the projectile wheret represents the time, in seconds, after which the projectile is launched andsrepresents the height of the projectile at timet.

S(t)= - 16t^2+117t+2

How long will it take for the projectile to return to the ground?How long will it take the projectile to reach its maximum height? What is the maximum height reached by the projectile?

Round all answers to one decimal place.
