Homework Statement
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?
Homework Equations
F=ma
Fx=Fgsinx
Fy=FgCosx
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.
