(4) Draw the Freebody Diagram for the below systems (make sure to redraw the object and remove everything it is "connected" to! (Free-body))
Include your axis.
Decompose any forces onto the axis you defined.
Pay attention to the direction a spring will act on the object. (Is it pushing/pulling?)
Assume springs start unstretched.
Write the appropriate equations for friction force, spring force, gravitational force, etc.
a) Spring force, gravitational force, etc.
