Answer:
The starting velocity.
Explanation:
We must understand that this equation comes from the following equation of kinematics.

where:
Vf = final velocity = 33 [m/s]
Vo = starting velocity [m/s]
a = acceleration = 3 [m/s²]
t = time = 30 [s]
So, these values can be assembly in the following way:
