If a ball is thrown vertically upward with an initial velocity of
160f(t)/(s)
, then its height after
t
seconds is
s=160t-16t^(2)
. (Consider up to be the positive direction.) (a) What is the maximum height (in ft) reached by the ball?
◻
ft
(b) What is the velocity (in
f(t)/(s)
) of the ball when it is
384ft
above the ground on its way up?
◻
f(t)/(s)
What is the velocity (in
f(t)/(s)
) of the ball when it is
384ft
above the ground on its way down?
◻
f(t)/(s)
