1. Friction does not violate the energy of conservation of law because Friction is
a force which works against the direction of speed. However, one can use
Newtons law of motion to prove this theory.

1. I would tell the friends to sit in the middle to minimize Moment of
Inertia, which is I=MR^2
2. No it would not be correct because anything that is larger than a point
mass will have that mass imputed to it's entire outer surface.

1. Acceleration is less than gravity because of air resistance. Air resistance is
proportional to speed, therefore, as speed increases air resistance increases,
causing acceleration to go d
