Haha yeah me too...that's why I'm doing it its good practice.

anglum said:Normal force then equals 24.4307N?
anglum said:Fn -53.9cos(34) -20.3 = 0
Fn = 53.9cos(34) + 20.3
Fn = 44.685 + 20.3
Fn = 64.9851N
anglum said:ok that is the correct answer
so our problem was we weren't calculating all 3 perpendicular forces... we were just finding one of them and using that as Fn...
however its all 3 of them equal to 0
