A 41 kg girl and a 6.5 kg sled are on the frictionless ice of a frozen lake, 18 m apart but connected by a rope of negligible mass. The girl exerts a horizontal 4.5 N force on the rope. What are the acceleration magnitudes of (a) the sled and (b) the girl? (c) How far from the girl's initial position do they meet?

I really only need part (c).

I have (a) = .6923 N and (b) = .1097 N

-Thank You!
