Thanks man!

Ok now i need help with the question on the bottom of the pic.

Chuck pulls his brother in a sled. Chucks brother and the sled have a combined mass of 50kg. On a flat surface, chuck pulls with 120 N 30 degrees above the horizontal. The coefficient of friction btwn the sled and the snow is .08. Find the acceleration of the sled. i drew my FBD but I am not...

See, i am almost certain there are very little if any calculations. Basically what is happening to the normal force with "spiderman" applying directional force. It all depends on the amount of force applied by spiderman and the gravitational pull on the box itself correct?

ignore the "a 65 kg box..." i just stress myself out to a point where i can't think staight. Can someone explain the spiderman problem to me?
