## Finding Speed from Work Graph

### Objective:
Find the change in velocity of a 239 g hockey puck subject to the force shown below.

### Graph Explanation:

The graph shown represents the force applied to a hockey puck as a function of the distance over which the force is applied.

- **X-axis (Distance in mm):** This axis represents the distance over which the force is applied, ranging from 0 to 800 millimeters.
- **Y-axis (Force in N):** This axis represents the magnitude of the force applied to the puck, ranging from 0 to 200 Newtons.

### Observations:
- From 0 to 100 mm, the force (in Newtons) remains at 0.
- From 100 mm to 700 mm, the force suddenly jumps to 160 N and remains constant.
- From 700 mm to 800 mm, the force drops back to 0 N.

This graph indicates that a constant force of 160 N is applied to the puck between 100 mm and 700 mm.

### Important Note:
- The direct application of physics principles is required to calculate the change in velocity using the work-energy theorem.
