[LO 21.4, 23.0, 23.2, 25.1] A skater extends her arms horizontally, holding a 5-kg mass in each hand. She is rotating about a vertical axis with an angular velocity of one revolution per second. If she drops her hands to her sides, what will the final angular velocity (in rev/s) be if the moment of inertia of her body remains approximately constant at 5 kg m?, and the distance of the masses from the axis changes from 1 m to 0.1 m?

A per son bends forward to lift a load with his back. To see that this is not a good way to lift, we will find the large induced force R = Rx(i) + Ry(j) occurring in the spine by lifting a 200-N object. The spine and the upper body are represented as a uniform horizontal rod of weight 350 N, pivoted at the base of the spine. The erector spinalis muscle, attached at a point 2/3 of the way up the spine, maintains the position of the back with tension T. The angle between the spine and this muscle theta = 12 degrees. Find the magnitude of force R at the base of the spine.
26 An object weighing 70 N is attached to the end of the rope, which is wound on a bobbin with a radius of 0.60 m and a mass of 4.50 kg. The coil is in the form of a solid disk and can rotate freely in the vertical plane about the horizontal axis passing through its centre. The object attached to the rope weighing 70 N is released at a height of 5.50 meters from the ground. Calculate the acceleration of the object.
