Please just answer this question: Qualitatively discuss what effect considering the resistance of the conducting rails would have on your estimate of terminal velocity.

(Note if it helps: I calculated an induced current of 0.049A for part b).

A conducting bar of mass m = 18.0 g and resistance R = 1.89 N slides down two conducting rails
that are frictionless and have no electrical resistance. These rails make an angle 0 = 40.0° with the
horizontal and are separated by a distance l = 20.0 cm, as shown. In addition, a uniform magnetic
field B = 712 mT is applied vertically upward. The bar is released from rest and slides down.

when it is moving at 85.0% of terminal speed?
