A 0.350 kilogram particle slides around a horizontal track. The track has a smooth vertical outer wall forming a circle with a radius of 1.50 meter. The particle is given an initial speed of 7.00 m/s. After one revolution, its speed has dropped to 5.00 m/s because of friction with the rough floor of the track.
(a) Determine the energy transformed from mechanical to internal in the system as a result of friction.

(b) Calculate what is the coefficient of kinetic friction.
(c) Find the total number of revolutions the particle makes before stopping?
