Question #2Determine an expression for the motion of the cylinder described in my first question to you(cylinder of radius 4 in, height 10 in, and weight 15 lb, water density 62.5 lb/ft3, r =1/3 ft.) if is released with 20% of its length above the water line with a veolocity of 5 ft/sec in a downward direction. Please give a summary of how this works, so I can understand it. Thank you, James.
