Initial me Final Em A hollow lightweight grooved disk whose moment of inertia is 2.0 x 10'3 kgom2 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 0.062 kg, and they are connected to each other bya spring. At a particular moment in time [the \"initial state\") the blocks are 0.36 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 a),- is 10 radians/s. The spring pulls the blocks toward each other, and at a later time (the "nal state\") the blocks are 0.12 m apart. Part 1 Now what is the angular speed (59-? Approximate the metal blocks as paint particles.
