Ranking Change in Momentum of Four Wheels

APPH12-NS7QGS

Four wheels (all mass distributed on edge) of equal mass, but different size, are moving along a road in the same direction. An equal braking force is applied tangent to the wheel and all wheels come to a stop in the same amount of time.

Rank the change in angular momentum (magnitude only) of the wheels from greatest to least.
