Body A in fig. weighs 102N, and body B weighs 32N. The coefficients of friction between A and the incline are us=0.56 and uk=0.25. Angle theta is 40 deg. Find the acceleration of the system if A is moving up the incline. the fig. is 90 deg. triangle where body A is on the hypotenuse and body B hanging parallel to the opposite.
