1. The figures show free-body diagrams (FBD) for an object of mass m. Write the x-y components of
Newton's second law. Write your equations in term of the magnitudes of the forces F,,F,... and any
angles defined in the diagram. One equation is shown to illustrate the procedure.

2. Since Fnet = mā, the acceleration's direction directly tells us information about the direction of the
net force. It is good practice to draw an "acceleration diagram" (i.e. a diagram with the acceleration
vector) next to the FBD. Then you can read the equations directly off of the diagrams. For example,
consider this acceleration diagram for the First Set from Q1:
Knowing the direction of a, what does that mean about the signs of both components of Fnet in the first
set of equations from Q1?
