A man was shot out of a cannon it was estimate to be a much as 36 ft. per second. if we assume that this cannon was pointed upward, then the man's height after t seconds would have been s(t)=-16t^2+ 36t+5
How high was the man initially?
Evaluate s(2) and Interpret what was found.
Use a symbolic approach to find the man's maximum height.
Using the symbolic approach find the time the man landed on the ground.
What is the relevant domain?
