A model rocket is launched with an initial velocity of 11[c] feet per second from the height of [a] feet. The functionmodels the path of the rocket where t represents the time, in seconds, after which the rocket is launched and s represents the height of the rocket at time t.

2. 1 How long will it take for the rocket to return to the ground?
3. 2 How long will it take the rocket to reach its maximum height? What is the maximum height reached by the rocket?

Round all answers to one decimal place.

Note: if [a]=2 and [c]=7, then

My PIN 28763

[a]=2 [b]=8 [c]=7 [d]=6 [e]=3
