Device Design

A marble is dropped into a piece of tubing the marble then continues to hit a hot wheels car.

The hot wheels car goes down a ramp and ramps into a ruler which spins and hits another ruler.

This ruler in turn cuts a piece of string that is wrapped around a banner dropping down a POWER T.

Calculations

Step One (marble collides with car) mgh = 1/2 mv² v = √(2gh) = 3.6 m/s m₁v₁ + m₂v₂ = m₁v₁’ + m₂v₂’ v₂’ = .5625 m/s

Step Two (car goes down track) mgh + 1/2mv² = 1/2 mv₂² v₂ = 2.89 m/s

Step Three (car collides with ruler) 1/2mv² = 1/2 Iω² ω = 18.9 rev/s

Conclusions

Project was fun but required a lot of effort

It was interesting to see how the principles of physics work out in real life
