152 The Laws of MotionP5.68Since it has a larger mass, we expect the 8.00-kg block to movedown the plane. The acceleration for both blocks should have thesame magnitude since they are joined together by a non-stretchingstring. Define up the left hand plane as positive for the 3.50-kgobject and down the right hand plane as positive for the 8.00-kgobject.FmamgTmaa mga111112222235 035 0∑∑=−°+==°−=:sin.in.FIG.
