Ten questions. The result tells you which lessons you may skip.
A disc rolls without slipping down a rough slope. How much work does the friction on it do?
A rigid wheel rolls without slipping at a steady speed on a level road. The friction on it is
A solid sphere rolls without slipping down a slope of \(37°\), with \(\sin 37° = 0.6\). Take \(g = 10\,\text{m/s}^2\). Its acceleration is
A ring, a disc and a solid sphere roll down the same slope from rest together. The order of arrival is
A solid cylinder of mass \(4\,\text{kg}\) is pulled at its axle by \(12\,\text{N}\) and rolls on a level floor. The friction on it is
The rear wheel of a car that is speeding up feels a friction from the road that points
A uniform disc unwinds from a string wound on its rim, with the upper end held fixed. Its acceleration is
A solid ball is struck through its centre at \(7\,\text{m/s}\) with no spin. When it starts to roll without slipping, its speed is
A uniform disc of mass \(8\,\text{kg}\) and radius \(0.5\,\text{m}\) rolls without slipping at \(3\,\text{m/s}\). Its angular momentum about the point of the ground it touches is
A uniform rod \(0.9\,\text{m}\) long hangs from a hinge at its top. Where should it be struck so that the hinge gives no impulse?
