Problem
A 1.5kg solid disk of radius 0.25m spins freely about its central axis at 12rad/s. A 0.40kg blob of putty is stuck to the rim and rotates with the disk. Determine the magnitude of the total angular momentum of the disk–putty system about the disk’s center at this instant. Give your answer to two significant figures.
