A smooth circular hoop with a radius of 0.900 m is placed flat onthe floor. A 0.350-kg particle slides around the inside edge of thehoop. The particle is given an initial speed of 7.50 m/s. After onerevolution, its speed has dropped to 5.00 m/s because of frictionwith the floor.
(a) Find the energy transformed from mechanical to internal in theparticleâhoopâfloor system as a result of friction in onerevolution.
(b) What is the total number of revolutions the particle makesbefore stopping? Assume the friction force remains constant duringthe entire motion.
