1. The problem statement, all variables and given/known data An 18kg cart is connected to a 12kg hanging block at the bottom of the incline (ignore friction) What is the magnitude of acceleration of the cart? 2. Relevant equations F=ma Fx=Fgsinx Fy=FgCosx 3. The attempt at a solution well without the hanging weight i calculatoed the force parallel to the plane to be 101.2 N and the force perpendicular to the plane is 144.5 N I tried adding the X force (101.2N) to the downward force of the weight on the pulley (176.4 ) and then dividing by the total masses. But I can never get the right answer its supposed to be 7.3 m/s*2 but I don't know how its obtained.
