1. See Attachment 2. F = ma 3. For the block on the incline plane, I know it has Fnormal, Fweight, and Ftension. While the one hanging has Ftension and Fweight. Fn = 6gcos30 ƩFx = 6gcos30 - T = 6a 6gsin30 - (2g +2a) = 6a 6gsin30 -2g = 8a 2g(3sin30 - 1) = 8a a = 1.225 T = 6gsin30 - 6a = 22.05N Is this correct? And when do I use negative acceleration versus positive acceleration?
