An object is thrown upwards from the top of a building, which is 1296 feet tall. The initial velocity is 3 feet per second. Use the position function below to find the height of the object when t=2 seconds. $s = - 16 t ^ { 2 } + 3 t + 1296$
A)58 feet
B)1354 feet
C)1226 feet
D)1238 feet
E)1366 feet

Substitute t=2 into the position function: $s = -16(2)^2 + 3(2) + 1296$. This simplifies to $s = -64 + 6 + 1296 = 1238$ feet.
