1. The problem statement, all variables and given/known data Block of mass mA = 2kg - lying on frictionless inclined plane with a slope of 20 degrees. connected to mA via frictionless, massless pulley and massless cord... mB = 3kg http://img152.imageshack.us/img152/8286/imag0103l.jpg [Broken] 2. Relevant equations F= Mass * Acceleration Acceleration = Mass / Force 3. The attempt at a solution so far all I can get is the free body diagrams.. would this follow a = Fga + Fgb / ma + mb? except I don't have force..
