, draw a free body diagram for the object when it is not in the water and another one when it is submerged in the water. Upload your diagrams (as a single image or document), or provide a description of the forces acting on the object for both situations and clearly indicate the directions of the forces. Only draw a big dot to represent the object. Draw the forces on the dot. (Artistic renditions of the lab set up is a waste of time and will receive a reduced grade.)

Apply Newton's 2nd Law to write the equations describing the forces drawn on the free body diagrams.

Use up and to the right as positive for your coordinate system. Using a different coordinate system will earn zero points.

Everyone needs to identify which situation you are describing/drawing. Clearly identify which situation for each equation. The two situations are 1) in air and 2) submerged in water.

If not providing a diagram, for directions use the words up, down, left, or right.
