A 2.30kg hoop 2.20m in diameter is rolling to the right without slipping on a horizontal floor at a steady 3.00rad/s .

Part A How fast is its center moving?

Part B What is the total kinetic energy of the hoop?

Part C Find the magnitude of the velocity vector of each of the following points, as viewed by a person at rest on the ground:

(i) the highest point on the hoop;

(ii) the lowest point on the hoop,

(iii) a point on the right side of the hoop, midway between the top and the bottom.
Separate your answers by commas.

Part D Find the magnitude of the velocity vector for each of the points in part (C), except as viewed by someone moving along with same velocity as the hoop.
