Initial state Final state A hollow lightweight grooved disk whose moment of inertia is 4.0 * 105 kg.m rotates with negligible friction around a vertical axis. Free to slide with negligible friction in the groove are two metal blocks, each with a mass of 0.066 kg, and they are connected to each other by a spring At a particular moment in time (the "initial state") the blocks are 0.30 m apart, with zero radial velocity (that is, they are not moving toward or away from each other). At this moment the angular speed of the disk is my is 11 radians/s. The spring pulls the blocks toward each other, and at a later time (the "final state") the blocks are 0.10 m apart. Part 1 Now what is the angular speed my? Approximate the metal blocks as point particles. radians/s Save for Later Attempts: 0 of 10 used Submit Answer Part 2 What is the change in the potential energy of the spring including sign?
