Two conducting rails 30 cm apart rest on a 5.0$\degree$ ramp. They are joined at the bottom by a $0.60 ~\Omega$ resistor, and at the top a copper bar of mass $0.040$ kg is laid across the rails. The whole apparatus is immersed in a vertical $0.55 ~\mathrm{T}$ field. What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails?
