1. A boy is standing on a frozen lake (i.e. no friction) holding a rope that is attached to his sled. He pulls on the rope and exerts a horizontal force of 5.2 N, pulling the sled toward him. If the boy's mass is 40 kg, the sled's mass is 8.4 kg, and they are initially 15 m apart, then

(a) What is the acceleration of the sled?

(b) What is the acceleration of the boy?

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