A 36 kg girl and a 9 kg sled are on the frictionless ice of a frozen lake, 20 m apart but connected by a rope of negligible mass. The girl exerts a horizontal force of 6 N on the rope.

a. What is the acceleration of the center of mass of the girl-sled system when the girl exerts a 6 N force on the rope?

b. How far from the girl’s initial position do they meet?
