A sled carrying a child is pulled with a force of 100 N in a direction 37.0° above the horizontal. Note: The sled is not going up a hill with a 37.0° incline - it is traveling on horizontal ground and the rope being pulled is angled at 37.0° with respect to the ground. The mass of the child and sled is 40.0 kg. If friction is negligible, the acceleration of the sled is closest to
