A ball is thrown straight up from the top of a tower that is 280 ft high with an initial velocity of 48 ft/s. The height of the
object can be modeled by the equation s ( t ) = -16 t2 + 48 t + 280. Determine the time(s) the ball is lower than the building. Express your answer in interval notation. In two or more sentences, describe your solution method.

Answer:
0 is an inflection point
1/4 is a local maximum.
Step-by-step explanation:
To begin with you find the first derivative of the function and get that
to find the critical points you equal the first derivative to 0 and get that
To find if they are maximums or local minimums you use the second derivative.
since is neither an inflection point, and since
then 1/4 is a maximum.
