**Physics Problem: Collision and Force Analysis**

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision.

*Question:*
What is the magnitude of the velocity, or final speed, of the car after the collision?

**Graph Analysis: Force vs. Time**
- **Axes:**
  - The horizontal axis represents Time (s), ranging from 0 to 0.10 seconds.
  - The vertical axis represents Force (N), ranging from 0 to 10 Newtons.

- **Curve Description:**
  - The force starts at 0 Newtons and rises linearly, peaking at 10 Newtons around 0.05 seconds.
  - After reaching the peak, the force decreases linearly back to 0 Newtons at 0.10 seconds.

*Calculation Section:*
- ***Final Speed = [Input Box] m/s***

**Tools:**
- Multiplier: x10

*Note: Students can use the impulse-momentum theorem to calculate the final speed of the car after the collision using the provided force-time graph.*
