Terminal Speed A conducting rod with length L, mass m, and resistance R moves without friction on

Question:

Terminal Speed A conducting rod with length L, mass m, and resistance R moves without friction on metal rails. A uniform magnetic field B is directed into the plane of the figure. The rod starts from rest and is acted on by a constant force F directed to the right. The rails are infinitely long and have negligible resistance.
(a) Graph the speed of the rod as a function of time.
(b) Find an expression for the terminal speed (the speed when the acceleration of the rod is zero).
