Q. An object, mass 2.96 kg, moves in a horizontal circle with a radius of 3.80 m. The object has an intial velocity of 32.6 m s-1. If the kinetic coefficient of friction between the object and the surface is 0.310, then the number of completed revolutions (integer value) that the mass will make before stopping, is equal to:

Assume the value of the gravitational acceleration as g = 9,81 ms-2.
