The rope shown in the figure attached hereto is wound around a cylinder of of mass 4.0 kg, radius 10 cm and I =0.020kgm2, where I is the moment of inertia about an axis along the cylinder axis. If the cylinder rolls without slipping, what the linear acceleration of its centre of mass?
A 7 kg sled is initially at rest on a horizontal road. The sled is pulled a distance of 3.5 m by a force of 37 N applied to the sled at an angle of 30o to the horizontal
An experiment you're designing needs a gas with = 1.60. You recall from your physics class that no individual gas has this value, but it occurs to you that you could produce a gas with = 1.60 by mixing together a monatomic gas and a diatomic gas. Wha..
A car with a total mass of 1.65*103 kg has wheels ofradius 35.0 cm and moment ofinertia 0.760 kg ·m2. Suppose that the wheels were then replaced byoversized wheels of the same shape and made of the same materials,but 49% wider and witha 49% larger..
