Okay, so dv/dt = v(const) or dv/dt = v(LB/mR) I still don't know how to solve for v. When I integrate dv/dt, do I get r(LB/mR)? and if so, what is r?

A conducting bar of length L = 21.2 cm and mass M = 60.0 g lies across a pair of conducting rails. The contact friction between the bar and the rails is negligible, but there is a resistor at one end with a value R = 30.0 Ohms. Initially the rod is given an initial speed of v0 = 64.0 meters per...
