1. The problem statement, all variables and given/known data An object of mass m1 =45kg sits on a horizontal frictionless table. A rope is attached to it , which runs horizontally to a frictionless pulley , then down to a hanging mass m2 = 5kg a) the acceleration of each mass b) the tension in the rope 2. Relevant equations a1=-a2 y component : F net = mg-t= ma2 x -component: F net : T=Ma1 3. The attempt at a solution I just wonder there are differeent acceleration and that realtionship of them was the negative sign only ?
