You'll get a position time graph like this. Press F1 to auto-scale the graph.

This is a position time graph. We want velocity (look at your data table). The slope of a position time graph gives you velocity. Press F3 to find and select the slope tool.

Press the left and right arrows to move the cursor. You'll notice a line that moves with it. The cursor is finding slope at each point in the graph. Align the slope bar so that it matches the graph.

After it is aligned, take the slope reading (at the bottom). This is the velocity.

You'll also need to find the mass of one coffee filter. Remember when you convert to Newtons: 100g = 1N.
