The Intelligent Side of Party Foul

• Conservation of Linear Momentum (Car and ball)

– mcarvcar+mballvb all= mcarvcar’+mballvball’

• Conservation of Angular Momentum (Pendulum and cup)

– Ipen.ωpen. + Icupωcup = Ipenωpen’ +Icupωcup’

• Gravitational Potential Energy to Kinetic Energy(Ball rolling down ramp ; ball falling from cup)– mgh=½mv2

– Vfinal=√2gh/1+x ; vfinal=√2gh

– vfinal=√[2(9.81m/s2)(.11m)]/[3/2] ; vfinal=√2(9.81m/s2)(.34cm)– Vfinal=1.2m/s ; vfinal= 2.58m/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.
