Two people, one twice as massive as the other, try to play tug of war on a nearly frictionless, level, icy surface. When they begin to tug, they are 12 m apart. They tug by pulling the rope hand over hand, until their hands meet along the rope. How far does the heavier person slide?

Answer 1

X m.=Distance the heavier person moves
2x m.= Lighter person distance.

x + 2x = 12
3x = 12
X = 4 m.
