Solve the problem.
-A rock is propelled upward from the top of a building 60 feet tall at an initial velocity of 70 feet $p$ second. Give the function that describes the height of the rocket in terms of time $t$.
A) $f ( t ) = - 16 t ^ { 2 } + 60 t + 70$
B) $f ( t ) = - 16 t ^ { 2 } + 70 t + 60$
C) $f ( t ) = 16 t ^ { 2 } + 70 t + 60$
D) $f ( t ) = - 70 t ^ { 2 } + 16 t + 60$

The correct function that describes the height of the rock in terms of time $t$ is given by the equation of motion under gravity, which is $f(t) = -16t^2 + vt + h$, where $v$ is the initial velocity (70 feet per second) and $h$ is the initial height (60 feet). Thus, the correct equation is $f(t) = -16t^2 + 70t + 60$.
