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:__________ Part 1: (25p) momentum and collisions. If not explain why; if yes compute the angular velocity. Since angular momentum is conserved then we obtain: Part 2: (25p) dynamics of rotational motion. As they fall down the incline the disk rolls without slipping and the block slips without rolling and without friction. Question 2. 1. 2: (10p) write all equations of motion that would allow you to solve the whole problem. = 0 !! cos ! sin ! cos ! Part 3: (25p) energy of rotational motion. Problem 3. 1: a small bicycle is made of a front tire of mass m2, radius r2 and moment of inertia. I2 and a rear tire of mass m1, radius r1 and moment of inertia i1.
