Homework Help: Physics

Posted by Anonymous on Thursday, March 8, 2012 at 12:19pm.

A smooth circular hoop with a radius of 0.400 m is placed flat on the floor. A 0.450-kg particle slides around the inside edge of the hoop. The particle is given an initial speed of 8.50 m/s. After one revolution, its speed has dropped to 4.00 m/s because of friction with the floor.

a) Find the energy transformed from mechanical to internal in the particle—hoop—floor system as a result of friction in one revolution.
b) What is the total number of revolutions the particle makes before stopping? Assume the friction force remains constant during the entire motion.
