Help with the following question
**Scenario Description:**

Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York. There is negligible friction between his feet and the ice. A friend throws Olaf a ball with a mass of 0.400 kg that is traveling horizontally at 10.0 m/s. Olaf’s mass is 73.7 kg. 

**Question:**

*Part A:*  
If Olaf catches the ball, with what speed \(v_f\) do Olaf and the ball move afterward? Express your answer numerically in meters per second.

**Diagram Explanation:**

The diagram shows Olaf in two positions. In the first position, he is preparing to catch the ball, which is approaching him horizontally. In the second position, Olaf has caught the ball and moves backward slightly, demonstrating the conservation of momentum.

**Solution Input:**

There is a box labeled \(v_f = \) for inputting the final speed in meters per second. There is also a "Submit" button and a "Previous Answers" option for checking or resubmitting answers.

**Hints Available:**

Users can view hints by clicking the "View Available Hint(s)" option to aid in solving the problem. 

**Interactive Elements:**

- Submit button: To enter the calculated speed.
- Previous Answers: To review prior attempts.
