We are standing on the top of a 896 feet tall building and launch a small object upward. The object's
vertical position, measured in feet, after t seconds is h(t) = – 16t+ 160t + 896. What is the highest
point that the object reaches?

Respuesta :

h(t)=-16t+160t+896
Use -b/2a
a=-16
b=160
c=896
t= -160/2(-16) = 5 sec
It will reach it’s highest point at 5 seconds
= -16(5)^2 +160 (5) + 896
= 1296

The Answer is
1296ft
