WebApr 15, 2024 · A string is wrapped around a disk of mass m = 2.3 kg and radius R = 0.08 m. Starting from rest, you pull the string with a constant force F = 6 N along a nearly frictionless surface. At the instant when the center of the disk has moved a distance x = 0.12 m, your hand has moved a distance of d = 0.26 m. vcm (center of mass of velocity) … WebMay 15, 2016 · Subscribe. 28K views 6 years ago.
