An object is launched straight upward with an initial speed of 400 ft/sec from a height of 4 ft. The height of the object t seconds after launch can be modeled by s(t) = −16t2 + 400t + 4, where s(t) is the height measured in feet. a Determine the time required for the object to reach its maximum height. b. Determine the maximum height of the object. c. Determine the time required for the object to hit the ground. Round to 1 decimal place.
