<PRE><B>Question 159368</B>
a rocket is shot straight up from the ground with an initial velocity of 100 feet per second. How high will it be after 3 seconds? 
-----------
h(t) = -(1/2)gt^2 + vot + ho
h(t) = -(1/2)(32)t^2 + vot + ho
h(t) = -16t^2+100t
h(3) = -16(3^2) + 100*3
h(3) = 156 ft.
====================
