Homework Statement
Two cans of the same size, mass, and shape are released from a ramp at the same height. One of the cans has milk and the other has refried beans. Which will reach the bottom first?
Homework Equations
Ktotal = Ktranslation + Krotational
The Attempt at a Solution
Since they start at the same height, their total kinetic energy at the bottom is the same. The can of milk has a higher moment of inertia, so in order total kinetic energy to be the same, it has to have lower translational kinetic energy; therefore, a smaller velocity. So why does the can of milk still reach the bottom first?
