The solution begins by integrating the given velocity function to obtain the height function. This step illustrates the fundamental relationship between velocity $rate of change of position$ and position.

Definition: In kinematics, the position function is obtained by integrating the velocity function: h$t$ = ∫ v$t$ dt + C, where C is the initial position.

The first part of the problem asks to determine the balloon's height after two minutes. This is solved by evaluating the height function at t = 120 seconds.

Example: The height after 2 minutes is calculated as: h$120$ = 0.0005 × 120³ - 0.15 × 120² + 2000.
