Question

Suppose that an air cannon in the Punkin Chunkin contest whose muzzle is 5 feet above the ground fires a pumpkin at an angle of 45° to the horizontal with a muzzle velocity of 303 feet per second. The model s(t) = - 16t² +208t+5 can be used to estimate the heights of an object after t seconds.
(a) Determine the time at which the pumpkin is at a maximum height.
(b) Determine the maximum height of the pumpkin.
