I've been stuck on this problem for a while. Im not sure where to even begin.

A bike wheel is rotating with an angular velocity of 3.1 rev/s. If the coefficient of kinetic friction between the wheel and brakes is .87, then find the revolutions the wheel makes in coming to rest. The moment of inertia of the wheel is .24 kg/m and its radius is .32m.

Im especially confused on the part where the wheel comes to rest. Without a set distance or time, Im not sure where to start.
