1. The horizontal circular platform weighs 500 lb and has a radius ofgyration of kz = 8 ft from the z-axis passing through O. Theplatform is free to rotate about the z-axis and is initially at rest. Aperson having a weight of 150 lb begins to run along the edge in acircular path of radius 10 ft. If they maintain a speed of 4 ft/srelative to the platform, determine the angular velocity of the10 ftplatform. Neglect friction.I don't think we have dealt with relative velocity in thiscontext, but it follows our earlier relative velocity treatment.Here all speeds are in the t-direction. vp is the speed of theperson, and vp is the speed of the disk at the location of theperson. Then vp = vp + Vp/D, same as before. You are given vpp= 4 ft/s.
