A Rube-Goldberg device created by:
Taylor Schlotman, Andrea Sams, Katherine Bailey, and Nathan McDonough.

2. “8 The Great”
EF 151- Section c1.

3. CALCULATIONS! In the pulley (angular velocity): V = ωr mgh = (1/2)mv^2
The ball at its initial height (C.O.E.):
mgh = (1/2)mv^2
The ball collides with the bucket: m1v1 + m2v2 = (m1 + m2)v’
In the paper towel roll (torque): T = Iα
In the pulley (angular acceleration): T = Iα
Y: T – W = -mAy
X: Ax = αr
In the pulley (angular velocity): V = ωr
Ball rolling down incline:
PEi = mgh = (1/2)mv^2 + (1/2)I ω^2
Car in paper towel roll (center of mass):
R = (m1r1 + m2r2) / (m1 + m2)
