Question

A 3.20 kg hoop 2.20 m in diameter is rolling to the right without slipping on a horizontal floor at a steady 2.60 rad/s . Part A How fast is its center moving? v = m/s Request Answer Part B What is the total kinetic energy of the hoop? E = J Request Answer 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. vi,vii,viii = m/s Request Answer Part D This question will be shown after you complete previous question(s). Part E 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. Separate your answers by commas.

Answer 1

Mass

Diameter

Radius

Anguler velocity

Consider the speed of the center is

We know

Total energy
