2. A rigid sphere with mass 20 Kg and radius 0.6 m is free to rotate around a fixed axis passing through its center (I = 2/5 mR2). The sphere is initially at rest. A force of 4 N is applied at the edge (or equator) of the sphere, tangent to the sphere and perpendicular to the sphere radius, generating a constant torque for 3 s. (i) Calculate the magnitude of the angular acceleration of the sphere. (ii) Calculate the...

A uniform disk with mass m = 9.04 kg and radius R = 1.35 m lies in the x-y plane and centered at the origin. Three forces act in the +y-direction on the disk: 1) a force 309 N at the edge of the disk on the +x-axis, 2) a force 309 N at the edge of the disk on the –y-axis, and 3) a force 309 N acts at the edge of the disk at an angle θ =...

The L-shaped object(Figure 1) can be rotated in one of the
following three ways: case A, about the x axis; case B,
about the y axis; and case C, about the z axis
(which passes through the origin perpendicular to the plane of the
figure).
If the same torque ? is applied in each of these cases,
rank them in decreasing order of the resulting angular
acceleration.
