A large disk of mass of 6.2 kg and radius 25 cm rotates with an initial
angular speed of 155 RPM (rotations per minute). Next a snmall disk of
mass 2.4 and radius 18 cm is dropped onto the larger disc. The disks
come to a common final angular velocity after a brief collision. Compute
the energy lost in the collsion. ( Express your answer to 1decimal, No
units)
