6. ♡ ♡ A perfect conducting bar with mass m rests on a partial loop of wire as illustrated. The entire arrangement is in a uniform magnetic field as illustrated. The bar is given a brief initial kick to the right with speed vo. The loop that has resistance R. a) Determine an expression for the current in the loop. In what direction does the current flow? ♡ b) Does the bar move with constant speed after it has been pushed? If not will its speed increase or decrease as time passes? Explain your answers. c) Determine an expression for the speed of the bar as a function of time. Use this to determine an expression for the total distance traveled by the bar. Both expressions should only involve the problem variables plus constants. d) Use the previous results to determine an expression for the current that flows through the loop as a function of time. e) Determine the total energy dissipated by the current. Does this show that energy is conserved in this situation?
