[10 Points) The two disks shown below are connected by a belt which does not slip as disks rotate. Disk A has a radius of 0.50 m and a mass of 2.00 kg, while disk B has a radius of 0.75 m and unknown mass. For the two disks have the
same angular momentum, what must be the mass of disk B? Assume that disk A is being rotated with an angular speed
of 1.50 rev/s and treat the disks as uniform cylinders. (Hint: When two disks are connected by a belt that does not slip,
the linear speeds at the rim of each disk are equal.)
