Read the Question Below Please :)

A smooth circular hoop with a radius of 0.700 m is placed flat on the floor. A 0.375-kg particle slides around the inside edge of the hoop. The particle is given an initial speed of 10.00 m/s. After one revolution, its speed has dropped to 5.50 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.

_______J

(b) What is the total number of revolutions the particle makes before stopping? Assume the friction force remains constant during the entire motion.
