1. The problem statement, all variables and given/known data Find the normal force on an object, 80kg, which is being pulled by a force of 4000N. A) Up at an angle of 50 degrees, B) Down at an angle of 70 degrees 2. Relevant equations Fn = Fwcosx Fp = Fwsinx 3. The attempt at a solution A) Fp = Fwsinx Fp = 4000sin50 = 3064N (80*9.8) - 3064 = -2280N = 2280N B) Fp = 4000sin70 = 3758.8N (80*9.8) + 3758.8 = 4542.7N Is this correct?
