The problem states that Henry hits a hockey puck in the positive \(x\)-direction at time \( t \approx t_0 \). The puck is stopped by a net starting at time \( t \approx t_1 \). The question is about determining the acceleration curve of the hockey puck, ignoring friction.

### Analysis:
1. **Initial Acceleration**: When Henry hits the puck at \( t_0 \), it experiences a positive acceleration as it starts moving forward.
2. **Constant Velocity Phase**: After the initial hit, the puck moves with constant velocity because there is no friction acting on it (assuming we ignore friction).
3. **Deceleration Phase**: At time \( t_1 \), when the net stops the puck, it experiences a negative acceleration (deceleration) until it comes to rest.

### Acceleration Curve:
- The acceleration would initially show a spike when the puck is hit, followed by zero acceleration (constant velocity phase), and finally a negative acceleration spike when the puck is stopped by the net.

### Possible Acceleration Curve:
- The curve would look like a sharp positive spike at \( t_0 \), then flat at zero, followed by a sharp negative spike at \( t_1 \).

Do you need any specific graph details or further analysis on this? 

### Related Questions:
1. What is the velocity-time graph of the puck under the same conditions?
2. How would the acceleration curve change if friction were considered?
3. What would be the implications of varying net force on the puck's acceleration?
4. How would the acceleration curve differ if the puck were gradually slowed down instead of being stopped abruptly?
5. What are the forces acting on the puck during each phase of motion?

**Tip**: In kinematic problems, identifying each phase of motion and corresponding forces helps determine acceleration patterns correctly.

Henry hits a hockey puck in the positive x-direction at time t ≈ t0. The puck is then stopped by a net starting at time t ≈ t1. Which of the following curves could describe the acceleration of the hockey puck if we ignore any effects of friction?

Analyze the acceleration curve of a hockey puck hit in the positive x-direction and stopped by a net. The problem covers kinematic concepts, including acceleration and velocity changes, using Newton's laws of motion. Suitable for students in Grades 10-12.
