2010 F = ma Exam — Question 7

7. Harry Potter is sitting 2.0 meters from the center of a merry-go-round when Draco Malfoy casts a spell that glues Harry in place and then makes the merry-go-round start spinning on its axis. Harry has a mass of 50.0 kg and can withstand 5.0 g’s of acceleration before passing out. What is the magnitude of Harry’s angular momentum when he passes out? — Source: Question 7, 2010 F = ma Exam, © 2010 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
