A yo-yo of mass m and radius R is placed on a horizontal surface as shown. A massless string is wrapped around an axle of radius r. The string will be pulled horizontally to the right as shown with a force of constant magnitude F. There is sufficient friction (f) between the surface and the yo-yo for the yo-yo to roll without slipping. Assume that the moment of inertia of the yo-yo about its rotation axis is approximatelyI (1/2)mR2. Draw...

MR A pulley of mass 3M and radius R is mounted on ftictionless bearings and supported by a stand of mass 4M at rest on a table as shown to the right. The rotational inertia of this pulley about its axis is (3/2)MR2. Passing over the pulley is a massless cord supporting a block of mass M on the left and a block of mass 2M on the right. The cord does not slip on the pulley, so after the...
