Question
Radon (of mass 50 kg) is standing 1 meter from the center of a playground merry-go-round (I=30 kgm^2) that is at rest. She begins to walk one direction around the merry-go-round with velocity v with respect to the merry-go-round. Which of the following is true?
a) The total angular momentum of Radon and the merry-go-round is true
b)The angular momentum of the mgr will be conserved as Radon walks because there are no non conservative forces acting.
c) Radon's kinetic energy is equal to the rotational kinetic energy of the mgr?
d) Two of the above
e) All of the above
Explanation / Answer
d) Two of the above
