2. Overview Our Caboose travels down a ramp and is launched into the air
After colliding with the first domino, the others fall, causing the final domino to set off the mouse trap
Attached to the trap’s arm is a tongue depressor with a stamp on it
When the arm is released, the stamp is accelerated around, and the paper is stamped

3. Conservation of Energy, Projectile Motion, and Conservation of momentum
Caboose begins with only gravitational potential energy (GPE) that is transferred to kinetic energy (minimal energy is lost to friction)
Final velocity on ramp is initial velocity of its path as a projectile
Caboose’s velocity as a projectile contributes to its momentum before colliding with first domino (domino effect displays conservation of momentum)
Mouse trap has stored elastic potential energy (EPE) that is transferred to rotational kinetic energy when tripped

4. Design Construction Issues
All materials were brought from home or found in Estabrook 13
Obviously, duct tape was our one and only adhesive
Extra weight was needed to more consistently set off the trap
Construction Issues
Our initial obstacle was obeying the 0.3 m x 0.5 m x 0.3 m size requirement
In building the contraption, we found that the piece needed to set off the trap often missed the trap when it fell, hence the “guiders” constructed from tongue depressors
Additionally, the trap was not consistently set off when the final domino fell. When weight was added to increase the probability of the trap being set off, it disrupted the domino’s balance, and the bulkiness of the weight would obstruct the arm from fully rotating

5. Conclusions
Price of materials purchased specifically for project: $0.00
Estimated price of used materials: ~$8.00
Total time spent on project: ~7 hours
Frequency of successful stamp: ~75%
