A 75 g, 30-cm-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 10 g ball of clay traveling horizontally at 2.5 m/s hits and sticks to the very
bottom tip of the rod. To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate?
A 500g, 8-cm-diameter can is filled with uniform, dense food. It rolls across the floor at 1.0 m/s. What is the can's kinetic energy?
A skater holds her arms outstretched as she spins at . What is the speed of her hands if they are apart?
A 1.0 kg ball and a 2.0kg ball are connected by a 1.0 m rigid, massless rod. The rod is rotating about its center of mass at 20 rpm. What net torque will bring the balls to a halt in 5.0 s?
Calculate by direct integration the moment of inertia for a thin rod of mass M and length L about an axis located distance d from one end. Confirm that your answer agrees with Table 12.2 when d = 0 and when d = L /2.
