To give a 22-kg child a ride, two teenagers pull on a 3.7-kg sled with ropes Both teenagers pull with a force of 55 N at an angle of 35 ∘ relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N.

Part A.) Find the acceleration of the sled and child.
