Syllabus Scores A thin, light wire is wrapped around the rim of a wheel, as shown in the following figure. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.272 m. An object of mass 4.30 kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant acceleration.(Figure 1) Pearson eText Study Area Document Sharing User Settings Figure 1 of 1 Course Tools Pro
