Concept Question 3 (Georgetown Day School)

Target group: physics students in Classical Mechanics

2 balls, labeled A and B, having equal momentum, moment of inertia, and radii, are rolling without slipping across a table. They both encounter upward ramps of equal angle and height. The ramp for ball A is frictionless while the ramp for ball B is made of the same material as the table (that is, has the same friction characteristics as the table.) Do both balls rise to the same height on the ramps? See the figure below.
