Questions
A solid sphere is in rolling motion. In rolling motion a body possesses translational kinetic energy () as well as rotational kinetic energy () simultaneously. The ratio for the sphere is
detailed solution
Correct option is D
Translational kinetic energy of sphereKt = 12mvc2-----------------(i)Summation of translational and rotational kinetic energyKt+Kr = 12mvc2+12I0ω2For solid sphere, I0 = 25mr2 and in case of rollingvc= ωrIt means KtKt+Kr = mω2r2mω2r2+25mr2ω2 = 11+25 = 57Talk to our academic expert!
