Question

If a solid sphere of mass 1 kg and radius 0.1 m rolls with out sliping at a uniform velocity of 1 m/s along a straight line on a horizontal floor, the kinetic energy is

Accepted Answer

When body rolls over a smooth surface, it has liner K.e. and rotationl K.E.
∴ mv² + ω²
where ω = and I = mr² for solid sphere.
∴ K.E. = mv² +
= mv² + = mv² = mv² = × 1 × 1²
=
