The Intelligent Side of Party Foul Conservation of Linear Momentum (Car and ball) – m car v car +m ball v b all = m car v car ’+m ball v ball ’ Conservation of Angular Momentum (Pendulum and cup) – I pen. ω pen. + I cup ω cup = I pen ω pen ’ +I cup ω cup ’ Gravitational Potential Energy to Kinetic Energy (Ball rolling down ramp ; ball falling from cup) – mgh=½mv 2 – V final =√2gh/1+x ; v final =√2gh – v final =√[2(9.81 m/s 2 )(.11 m )]/[3/2] ; v final =√2(9.81 m/s 2 )(.34 cm ) – V final =1.2 m/s ; v final = 2.58 m/s Torque (Ball striking cup to flip it over) – τ=Iα and τ=r x F

Road Bumps The Mousetrap: can kill a mouse but cannot cut thread. The wood: either splits or the nails aren’t long enough. Stability: “just make the base bigger.” The solution for any problem: Duct tape.

Good Riddance, Party Foul. What started as a “simple idea” turned out to be not so simple. Worked out all of the problems to the point of functionality. Completed the goal and worked well together.
