Question 344763: If a baseball is projected upward from ground level with an initial velocity of 160 feet per second, then its height is a function of time, given by s= -16t^2+160t.
What is the maximum height reached by the ball?

Take a derivative.
v+=+ds%2Fdt+=+-32t+%2B+160
At the top point the speed is 0.
-32t+%2B+160+=+0
t+=+5
Evaluate the original function
s%285%29+=+400
Done!
