To give a 20-kg child a ride, two teenagers pull on a 3.6-kg sled with ropes, as indicated in the figure. 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.

1. I think you're missing the question part.

In any case. You need to break up the force exerted by the teenagers into the horizontal and vertical components. The horizontal force is the only one that makes the sled move. you can make a right angled triangle if you draw it out and use Cos 35 degrees to help find the magnitude of the side you want.

You could probably work out the acceleration if you wanted from that.
