Unformatted text preview: 25.0 m diameter that turns at a constant angular velocity once every 10 minutes. What is the total work done on the person between the lowest and the highest point she reaches during one revolution of the wheel? [Use g = 10.0 m/s 2 ] a) No work is done. b) 15 kJ. c) 30 kJ. 4. [2 points] The maximal angular velocity of a centrifuge is determined by the maximal centripetal force its walls can generate. If two otherwise identical centrifuges differ by a factor four in diameter, the larger centrifuge can be operated with a maximal safe angular velocity that is: a) The same as large as for the smaller one. b) Twice as large as for the smaller one. c) Half as large as for the smaller one....
