asked 03/22/21please help me with my physics homework
A spherical object (with non-uniform density) of mass 16 kg and radius 0.14 m rolls along a horizontal surface at a constant linear speed without slipping. The moment of inertia of the object about a diameter is 0.25 M R2 .
a) The object’s rotational kinetic energy about its own center is what fraction of the object’s total kinetic energy?
first attempt: .444
second attempt: .44
third attempt: 88715401/200000000
