can you please finish this code.

Defining Net Force: 1. What force is acting on the ball? Define this force, as a vector, in the space below.

2. Translate this expression to VPython coding language in the box below and change the value inside the vector for Fnet in your code.

Updating Momentum from Net Force: Since there is a net force acting on the ball, modeling the balls motion is not as simple as just updating the position of the ball. The balls momentum will also need to be updated BEFORE each new position.

3. Write the mathematical equation to update momentum in the box below. Use the following variables: Fnet (net force), pi (initial momentum), pf (final momentum), and t (change in time).

4. Translate the above equation into VPython notation in the box below. Add this expression to the while loop in your program.

Updating Position from Momentum:

5. Write the mathematical equation to update position in the box below. Use the following variables: ri (initial position), rf (final position), p (momentum), m (mass), and t (change in time).

6. Translate the above equation into VPython notation in the box below. Add this expression to the while loop in your program.
