Angular velocity versus time for the rolling disk.
Angular velocity versus time for the rolling disk.
A uniform solid disk of mass \(M = 4.0\text{ kg}\) and radius \(R = 0.50\text{ m}\) rolls without slipping up an incline. The graph shows the disk's instantaneous angular velocity \(\omega\) as a function of time \(t\). Between \(t = 0\text{ s}\) and \(t = 2.0\text{ s}\), what is the net work done on the disk?
