Problem

A solid sphere of mass

2.0\,\text{kg}

and radius

0.15\,\text{m}

starts from rest and rolls without slipping down a ramp, dropping through a vertical height of

1.2\,\text{m}

. What is the sphere’s angular speed

\omega

when it reaches the bottom of the ramp? a)

34\,\text{rad}\!/\!\text{s}

46\,\text{rad}\!/\!\text{s}

30\,\text{rad}\!/\!\text{s}

23\,\text{rad}\!/\!\text{s}
