1.) Find the kinetic energy K of the rotatingparticle. Express your answer in terms of m, r,and ?.

2.) Find the moment of inertia Ihoop of a hoop ofradius r and mass m with respect to an axisperpendicular to the hoop and passing through itscenter. Express your answer in termsof m and r.

Consider a particle of mass m that is revolving with angular speed w around an axis. The perpendicular distance from the particle to the axis is r. (Figure 1) Figure 3 < 1 of 2 >
