To give a 17 kg child a ride, two teenagers pull on a 3.6 kg sled with ropes, as shown in the image below. Both teenagers pull with a force of 55N at an angle of 35 relative to the forward direction of motion. In addition, the snow exerts a frictional force on the sled opposite the direction of motion with a magnitude of 57N. What is the acceleration of the sled? 55 N 35 5/ N 55 N O a ) 1 m /s 2 O b ) 2 m /s 2 O c) 1.5 m / s 2 O d) 15.15 m /s 2
