A thin ring and a solid disc of same mass and radius start rolling from rest down an inclined plane. Ratio of their velocities at the bottom is:

1:√(4/3)

√2:1

1:1

√(3/4):1

The radius of gyration of a solid sphere of radius R about its diameter is:

The relationship between angular velocity ω, linear velocity v, and radius r is:
