1. The problem statement, all variables and given/known data Find the normal force on an object, 80kg, which is being pulled up by a force of 4000N at an angle of: A) Up at 50 degrees. B) Down at an angle of 70 degrees. 2. Relevant equations Fw = mg Fsinx Fcosx 3. The attempt at a solution A) Fn = 784 - 4000sin50 = -2280 = 2280N B) Fn = 784 + 4000sin70 = 4543N Is this correct?
