Common Types of Puzzles and Their Solutions
1. Calculating the Speed of the Coaster at Different Points
One common challenge is determining the coaster’s velocity at various track points.
Solution Approach:
- Identify the initial height of the coaster and potential energy.
- Apply conservation of energy: total energy remains constant (neglecting friction).
- Use the formula:
Potential Energy + Kinetic Energy = Constant
- At any point:
mgh = ½ mv² + mgh₂
- Simplify to find v:
v = √(2g(h₁ - h₂))
Example: If the initial height is 20 meters, and the coaster drops to 5 meters:
- v = √(2 9.8 (20 - 5)) = √(2 9.8 15) ≈ √(294) ≈ 17.15 m/s
2. Designing the Track for Safe and Exciting Rides
Designing a track involves balancing thrill with safety, ensuring the coaster maintains adequate speed without excessive G-forces.
Solution Tips:
- Set initial height to maximize potential energy, providing sufficient speed.
- Include gentle curves to reduce lateral G-forces.
- Incorporate loops and drops to increase excitement, calculating forces to prevent discomfort.
- Use physics formulas to estimate maximum G-forces:
G = (v² / r) / g + 1
- Adjust track radius (r) and speed (v) to keep G within safe limits (~3-5 G).
3. Understanding Energy Conservation and Losses
While the answer key assumes ideal conditions, real scenarios include energy losses due to friction and air resistance.
Solution Strategies:
- Account for energy loss by reducing the initial potential energy or adjusting expected speeds.
- Use the formula:
Potential Energy - Energy Losses = Kinetic Energy
- Estimate energy losses based on track length and materials for more realistic predictions.
