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. Equations/values that you may find useful: s(t)=so+vot+ at2 v(t) v0 + at. 0(t) = 00 + co0t + a t2 (0(t) = (00 + a t v=rco, ataii=ra t = r x f = dl/dt=la. Solid cylinder or disk: i = mr2. In (e) i loliow cylinder (0 solid cylinder (g) thin wailed hollow (h) solid sphere (i) thin \valied hollow. Two boxes linked by a compressed spring lie initially at rest on a frictionless, horizontal surface. One box has mass in and the other has mass 3m. The spring is released and boxes slide away from each other toward frictioriless inclines adjoining the flat.
