Initial state Final state A hollow lightweight grooved disk whose moment of inertia is 2.0 x 103 kg-m² 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 0.074 kg. and they are connected to each other by a spring. At a particular moment in time (the "initial state") the blocks are 0.24 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, is 13 radians/s. The spring pulls the blocks toward each other, and at a later time (the "final state") the blocks are 0.08 m apart. Part 1 x Your answer is incorrect. Now what is the angular speed ay? Approximate the metal blocks as point particles. 00y= 46.42 radians/s T Part 2 What is the change in the potential energy of the spring, including sign? AU =
