A 38 kg girl and an 8.4 kg sled are on the frictionless ice of a frozen lake, 16 m apart bu connected by a rope of negligible mass. The girl exerts a horozontal 4.7 force on the rope.
(a) What is the acceleration of the girl?
m/s2
(b) What is the acceleration of the sled?
m/s2

(c) How far from the girl's initial position do they meet?
m
