A 40-kg firl and an 8.4-kg sled are on the surface of a frozen lake, 15 m apart. By means of a rope the girl exerts a 5.2-N force on the sled, pulling it toward her.

(a) What is the acceleration of the sled?

(b) what is the acceleration of the girl?

(c) How far from the girl's intial position do they meet, assuming the force to remain constant? Assume that no frictional forces act.
