Solution
Correct Answer:
2:3
- Translational Kinetic Energy: Kt=21mv2.
- Rotational Kinetic Energy: Kr=21Iω2. For a solid cylinder, I=21mr2. In pure rolling, v=rω⟹ω=v/r. Kr=21(21mr2)(rv)2=41mv2
- Total Kinetic Energy: Ktotal=Kt+Kr=21mv2+41mv2=43mv2.
- Ratio calculation: Ratio=KtotalKt=43mv221mv2=21⋅34=32.
