Homework Statement
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
Homework Equations
a1=-a2
y component : F net = mg-t= ma2
x -component: F net : T=Ma1
The Attempt at a Solution
I just wonder there are differeent acceleration and that realtionship of them was the negative sign only ?
