Two skaters of mass m1=50kg and m2=70kg are standing motionless on a horizontal ice surface. They are initially a distance L=7.0 meters apart. They hold a massless rope between them. After pulling the rope, the skater of mass m1 has moved a distance l=2.0 meters away from his initial position. We can completely neglect friction in this problem.

What is the distance L' between the two skaters when the skater of mass m1 has moved a distance l? (in meters)

L'=
