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
