Motional emf problem on inclined plane

[yankans]

Homework Statement

a straight horizontal rod slides along parallel conducting rails at an angle with the horizontal of 30 degrees (inclined plane). The rails are connected at the bottom by a horizontal rail so that the rod and rails form a closed rectangular loop. A uniform vertical field exists throughout the region.
assume: rod remains in contact w/ rails as it slides down rails. rod experiences no friction/air drag. Rails and rod have negligible resistance. g = 9.8m/s^2.
a)if velocity of the rod is 4.6m/s, what is the current through the resistor? answer in mA.
b) what is the terminal velocity of the rod? (in m/s)

note: this is like a motional emf problem - the rod on rails
and
rod = 71 g in mass, moving at 4.6m/s
magnetic field = 0.16 straight down
resistor = 6.8 ohms

Homework Equations

F magnetic field = IBl where l is lowercase L, the width btwn rails
Emf = Blv
magnetic flux = Blx

The Attempt at a Solution

I honestly have no idea where to start this problem...

The conductor is moving with velocity v in a B field. Current is induced.

Also, there is a force on the conductor related to I x B.
