64. A solid cube of wood of side 2a and mass M is resting on a horizontal surface. The cube is constrained to rotate about a fixed axis AB (Fig. P11.64). A bullet of mass m and speed v is shot at the face opposite ABCD at a height of 4a/3. The bullet becomes embedded in the cube. Find the minimum value of v required to tip the cube so that it falls on face ABCD. Assume m ,, M.

31 A solid cube of side 2a and mass M is sliding on a frictionless surface with uniform velocity v with arrow, as shown in Figure a. It hits a small obstacle at the end of the table that causes the cube to tilt as shown in Figure b. Find the minimum value of the magnitude of v with arrow such that the cube tips over and falls off the table. Note: The cube undergoes an inelastic...

A uniform door initially at rest has a width W = 1.5m and mass M= 20 kg. The door is hinged on one side and can freely rotate about the hinges without friction. A policeman fires a bullet, m, = 15 g into the door at a speed v. = 500m/s. The bullet takes a horizontal path and strikes the door in a perpendicular direction at the exact center. The moment of inertia of the door about an axis passing...

4) Figures 4A (side view) and 4B (overhead view) illustrates a uniform solid cylinder having mass M and radius R. The cylinder is positioned on a horizontal floor having sufficient friction to ensure that the cylinder can roll without slipping. The cylinder includes a mass-less yoke that is fixed to the symmetric axis of the cylinder and acts as a rolling friction-less pivot for the cylinder. An ideal spring having spring constant K is attached to the yoke at one...
