From experiments, the maximum acceleration a human can withstand for 1 minute is 10g or 10 times the acceleration due to gravity. Many experiments have a human test subject sit into a seat which is moved in a large circle at very high speeds. If the subject is 15 m from the center of the rotation and has a centripetal acceleration of 10g, determine a) the speed the subject must be moving at, b) the angular velocity o, and c) the period of rotation. (2 points) [38.3 m/s, 2.56 rad/s, 2.45 s] A string can support a 25 kg hanging mass before breaking (i.e. you tie a mass >25 kg to the string and let it hang down, the string will break). Using that string, you attach a 3.5 ko mass and rotate the mass horizontally on a flat, frictionless, table in a circle with a radius of 0.75 m. At what speed will the mass cause the string to break?
