A solid sphere and a hollow sphere of equal mass and radius are placed over a rough horizontal surface after rotating it about its mass centre with same angular velocity w0. Once the pure rolling starts let v1 and v2 be the linear speeds of their centre of mass. Then:
- v1 = v2
- v1 > v2
- v1 < v2
- data is insufficient
Answer
(C) v 1 2
