A spherical object with a moment of inertia of 0.576mr 2 starts from rest rollin

Question

A spherical object with a moment of inertia of 0.576mr2starts from rest rolling down a 3.04-m high incline. If the sphere is rolling without slipping, what is its linear speed at the bottom of the incline?(Answer with at least three significant figures.)

Explanation / Answer

0.5*Iw^2+0.5*mv^2=mgh

since v=w*r

==>0.5*1.567 v^2=g*h

==> v=6.16 m/s
