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 [tex]F_k[/tex]. The experiment is performed in a spacecraft drifting inspace. Find the speed of the bead at any subsequent time t.
Ok so you need to find the velocity of the object.
Well the acceleration would be: [tex] a = -F_k v^2 / r [/tex]
To find velocity, you would have to integrate that...
[tex]dv/dt = \int -F_k v^2 / r [/tex]
and that is...
[tex]v^-2 F_k r^-1[/tex]
now what do i do?
