The projectile motion of an object can be modified using s(t) = gt^2 + V0t + S0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, V0 is the initial velocity, and S0 is the initial height. The acceleration due to gravity is -4.9 m/s^2.

A rocket is launched from the ground at am initial velocity of 39.2 meters per second. Which equation can be used to model the height of the rocket after t seconds?

A.) s(t) = -4.9t^2 + 39.2
B.) s(t) = -4.9t^2 + 39.2t
C.) s(t) = -4.9t^2 + 39.2t + 39.2
D.) s(t) = -4.9t^2 + 39.2t - 39.2
