1. The problem statement, all variables and given/known data A person pulls on a rope attached to a 5 kg sled. The rope makes an angle of 30 degrees with the horizontal. Sled accelerates horizontally at 1.7 m/s^2. There is no friction. 2. Relevant equations ma = Fnet mg = Fgravity 3. The attempt at a solution Fnorm = earth force up on sled Fr = the force of the rope of the sled being pulled The x and y components for Fr would be y = Frsinθ and x=Frcosθ. Vector of Fnorm = <0, Fnorm> Vector of Fg = <0, -50> Vector of Fr = <Frcos30, Frsin30> Fnetx => 8.5 = Frcos30 Fnety => 0 = Fc - 50 + Frsin30 So I got this far and starting doing algebraic stuff to solve for Fr and then plugging that into the second equation. From there, I solved for Fc, and the value was 45.095 N. And from the Fnetx equation, Fr = 9.8 N. However, when I added all the magnitudes of forces, my answer does not equal to the Fnet, which is ma = 8.5 N. Can someone help me with this? Have I forgotten something? Am I even doing this right?
