Question 1151497
A water balloon thrown vertically in the air reaches its peak height after 2 seconds.
 If its height, as a function of time, is given by h(t)=-16t^2+bt+6, then find the value of b.
:
Using the axis of symmetry formula; t = -b/(2a) where
{{{(-b)/(2*-16)}}} = 2
:
-b = 2*-32
b = 64 ft per second
