Question

Based on the graph readings, what is the average acceleration and average force?

3. Be sure that the force sensor has been calibrated, and also be sure to click Rezero sensor with nothing
pulling on it before taking any measurements.
4. Find the amount of mass in coins so that the IOLab just barely doesn't move when the coins are hung over
the edge of the smooth surface.
5. Click Record and give the IOLab a brief push towards the right, and release. Let the IOLab move to the right
for a few seconds, and then click Stop.
6. Change the scale of the velocity vs. time graph if necessary to display it as clearly as possible.
Question 2-6: Is the velocity constant after the IOLab is released? How do you know?
The velocity is constant after pushed up until the point where I stop the recording. The graph
shows a constant reading where the IOLab is moving constantly. The initial reading is spiked a
little from the initial push.
