a hollow lightweight grooved disk whose moment of inertia is 3.5*10^-3 kgm^2 rotates with negligible friction around a vertical axis. free to slide with negligible friction in the groove are two metal block each with a mass of 0.078 kg, and they are connected to each other by a spring. at a particular moment in time the blocks are 0.42m apart, with zero radical velocity. at this moment the angular speed of the disk is 10 rad/s. the spring pulls the blocks toward each other, and at a later time the blocks are 0.14 m apart. Now what is the angular speed ωf? Approximate the metal blocks as point particles.
ωf= Type your answer here radians/s
