Problem

A solid cylinder of mass

2.0\,\text{kg}

and radius

0.20\,\text{m}

and a thin hoop of mass

1.0\,\text{kg}

and the same radius start from rest at the top of a

1.5\,\text{m}

-high ramp and roll without slipping down the incline. Using

g = 9.8\,\text{m/s}^2

, calculate the speed of each object at the bottom and state which arrives first.
