What are the acceleration magnitudes of the sled and the girl?

A 40 kg girl and a 5.8 kg sled are on the frictionless ice of a frozen lake, 20 m apart but connected by a rope of negligible m. The girl exerts a horizontal 4.3 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?
