Document Summary
Do not fill out the information below until instructed to do so! All work must be shown to get credit for the answer marked. Put your initials here after reading the above instructions:__________ In the following the system refers to the object+projectile system. nail. Identify the forces external to the system. Table to be filled by the graders. Forces are gravity and whatever force the nail is exerting. Yes, because there are not any non- conservative forces left after the collision. Li = lp = (icm + md 2 )!f ! Question 1. 1. 7: (8p) find how much the center of mass of the object will raise. Part 2: (35p) angular momentum. Problem 2. 1: i the middle of space a massless support structure holds two axes. The angular velocity of disk 1 is w1. Find the angular velocity of rotation of the system around its center of mass. 2!2 = i and because both disk rotate without slipping we get r.
