The long, narrow rectangular loop of wire shown above has vertical height H,
length D, and resistance R. The loop is mounted on an insulated stand
attached to a glider, which moves on a frictionless horizontal air track with an
inital speed of $v_o$ to the right. The loop and glider have a combined mass m.
The loop enters a long, narrow region of uniform magnetic field B, directed
out of the page toward the reader. Express your answers to the parts below in
terms of B, D, H, R, m, and $v_o$.
