a hollow sphere of mass M and radius r is in pure rolling on the horizontal surface the ratio of difference and translational kinetic energy and rotational kinetic energy to the total kinetic energy of the hollow sphere will be
Answers
The ratio of difference of translational kinetic energy and rotational kinetic energy to the total kinetic energy is 1/5
Explanation:
Given:
A hollow sphere of mass m and radius r is in pure rolling on horizontal surface
To find out:
The ratio of difference of translational kinetic energy and rotational kinetic energy to the total kinetic energy
Solution:
We know that the moment of inertia of hollow sphere
If the sphere is in pure rolling and its velocity is then its angular velocity
The total kinetic energy will be the sum of rotational and translational kinetic energy
The difference of translational and rotational kinetic energy is
Therefore, the ratio
Hope this answer is helpful.
