Asolid sphere with a moment of inertia of 2.20 kgm2 is rolling along the ground (without slipping) with an angular velocity of 15.1 rad/s . find (a) its rotational kinetic energy and (b) its translational kinetic energy.

Explanation:

It is given that,

Moment of inertia of a solid sphere,

Angular velocity of the solid sphere,

(a) The rotational kinetic energy of the solid sphere is given by :

(b) The translational kinetic energy of the solid sphere is given by :

Moment of inertia of solid sphere is :

Hence, this is required solution.

the first step is making objective observations.

they have to be based on a certain event and can be confirmed by others if it is right or not.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
