Document Summary
You may use two 3 x 5 card on which you have your favorite equations. You also may use a calculator but please do not share calculators: all cell phones and other communication devices must be shut off and out of sight, there are altogether 20 multiple choice questions. F = ma = r f = dl/dt=i hollow sphere: i = 2/3 mr2. Solid cylinder or disk: i = mr2. Fk = kn w = ( 2 1) g = 9. 8 m/s2 uspring = kx2 hoop: i = mr2. F = u impulse j = f. dt = (cid:4)p ip = icm + md2. W = k p = w/ t = f. v krot = i 2. Two boxes linked by a compressed spring lie initially at rest on a frictionless, horizontal surface. One box has mass m and the other has mass 3m. The spring is released and boxes slide away from each other toward frictionless inclines adjoining the flat.
