A 220 kg hoop 200 m in diameter is rolling to the right, Ask an Expert

Academics

A 2.20 kg hoop 2.00 m in diameter is rolling to the right without slipping on a horizontal floor at a steady 2.40{\rm rad/s} .

1- How fast is its center moving?

2- What is the total kinetic energy of the hoop?

3- 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.

4- 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.
