What is the maximum height attained by an arrow if the arrow was fired into the air from the top of a building that is 120 feet tall. The arrow had an initial velocity of 64 feet per second. The distance in feet of the arrow from the ground is given by (st)= -16t^2+64t+120?
***
(st)= -16t^2+64t+120
complete the square:
(st)= -16(t^2-4t+4)+64+120
(st)= -16(t-2)^2+184
What is the maximum height attained by an arrow? 184 ft, 2 sec after being fired.
