Unformatted text preview: It runs over a pulley and supports a 10.0kg mass, Find the torque that the cable exerts on the wench. 4. A potter's wheel with a moment of inertia of 0.100 kg·m 2 is spinning at 3.00rev/s when the potter drops a cylindrical hunk of clay on to it at the center. The hunk of clay has a mass of 4.00kg and a diameter of 15.0cm. Find (a)the moment of inertia of the hunk of clay about its central axis and (b)the rotational speed of the wheel and the clay just after it is put on the wheel. = 30˚ M = 10.0kg θ R = 15.0cm 3 5. A 50.0kg athlete doing a push-up lies horizontally with only her hands and feet touching the ground. Her center of mass is 60% of the way from her toes to her head and her hands are 85% of the way. Find the force that she must exert on the ground to do the push-up....
