A object of mass m = 1.25 kilogram moves in a horizontal circle of radius r = 1.56 meter on a rough table. It is attached to a horizontal string fixed at the center of the circle. The speed of the object is initially 3.85 m/s. After completing one full trip around the circle, the speed of the object is 2.50 m/s. Determine the energy dissipated by friction during that one revolution in Joules.
Find what is the coefficient of kinetic friction?
Find how many more revolutions will the object be making before coming to rest?
