A three disks are released at the same time at the top of an inclined plane. Let disk 1 have a mass M and a radius R, disk 2 have a mass M and a radius 2R, and disk 3 have a mass 2M and a radius R.
Find the rank the three disks in the order in which they finish the race?
Determine the rank from largest to smallest time for the race. To rank items as equivalent, overlap them.
