If a ball is thrown vertically upward with an initial velocity of
160f(t)/(s), then its height after
tseconds 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
384ftabove the ground on its way up?
◻
f(t)/(s)What is the velocity (in
f(t)/(s)) of the ball when it is
384ftabove the ground on its way down?
◻
f(t)/(s)
