If a ball is thrown directly upward with a velocity of 80 ft/s, its height (in feet) after tseconds is given by y= 80t-16t2 . What is the maximum height attained by the ball?

Already have an account? Log in
,its height (in feet) after 
seconds is given by
.find the velocity when 
.
. Isaac was holding a stopwatch and recorded that the time it took for the ball to reach the ground was 
. Isaac bet that the ball had reached its maximum height before 
second. Angelica bet that it's not possible and bet that it reached its maximum height after 
where acceleration due to gravity is 
and 
is the initial velocity and height from the ground, respectively.
