Asolid sphere with mass, m, and radius, r, rolls along a level surface without slipping with a linear speed, v. what is the ratio of rotational to linear kinetic energy

Explanation:

given,

mass of solid sphere = M

radius = R

linear speed = v

now,

Linear Kinetic energy

...............(1)

Rotational kinetic energy

moment of inertia of the solid sphere

and v = R ω

............(2)

ration of rotational and Kinetic energy

hence, ratio of rotational to linear kinetic energy is equal to 2/5.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

i think the answer is a, hope this : )
