Question

A ball is thrown vertically upward. After tseconds, its height h (in feet) is given by the function
h(t)=96t-16t^2
. After how long will it reach its maximum height?
Do not round your answer

Answer 1

use diff calculas
d/dt(h)=96-32t
d2/dt2=-32
equating d/dt(h)=0
give 96-32t=0
t=3 sec

Answer 2
