Chapter 8, Problem 17(choose chapter or problem)
A smooth circular hoop with a radius of 0.500 m isplaced flat on the floor. A 0.400-kg particle slidesaround the inside edge of the hoop. The particle isgiven an initial speed of 8.00 m/s. After one revolution,its speed has dropped to 6.00 m/s because of frictionwith the floor. (a) Find the energy transformedfrom mechanical to internal in the particlehoopfloor system as a result of friction in one revolution.(b) What is the total number of revolutions the particlemakes before stopping? Assume the friction forceremains constant during the entire motion.
