gdaunton Posted October 6, 2013 Share Posted October 6, 2013 I'm having trouble with question #9 for a it's just a simple normal force question with a block on an angle. So I did the usual mgcos(angle) = Fnormal and it didn't work. for b I used Fhor - mgsin(angle) = ma, solved for the acceleration and it also didn't work. I'm I missing something here?
