1. A sled is pulled at a constant velocity across a horizontal snow surface. If a force of 8.0 x 10^1 N is being applied to the sled rope at an angle of 53 degrees to the ground, what is the force of friction between the sled and the snow?

A. 83 N

B. 64 N

C. 48 N

D. 42 N

2. A trapeze artist weighs 8.00x10^2 N. The artist is momentarily held to one side of a swing by a partner so that both of the swing ropes are at an angle of 30 degrees with the vertical. In such a condition of static equilibrium, what is the horizontal force being applied by the partner?

A. 924 N

B. 433 N

C. 196 N

D. 610 N

2. Relevant equations

I don't know any formulas to use for this.

3. The attempt at a solution

I'm sorry, but if I knew what formula to use, I could probably do it. I can't find any formulas that include angles in the section.
