Consider a bead of mass m that is free to move on a thin, circular wire of radius r. The bead is given an initial speed v0 and there is a coefficient of kinetic friction us. The experiment is performed in a spacecraft drifting in space. Find the speed of the bead at any subsequent time t.
I did the following:
fk= m*a= m * dv/dt
v(t)= v0 - m * dv/dt
But I bet that is not the answer... Could somebody please help?
