Question



The graph above depicts the velocity of an unmanned wheeled cart over time. Two opposing forces acted on the cart during the course of the investigation. What is the BEST conclusion as supported by the data in the graph?

Answer 1

I can't see the graph you mention — could you upload it or describe the velocity–time shape (e.g., constant, increasing, decreasing, and the order of those segments)?

Here is how to decide once you can describe the graph:

- Constant velocity (horizontal v–t line) means net force = 0, so the two opposing forces are equal.
- Changing velocity (slope ≠ 0, speeding up or slowing down) means net force ≠ 0, so the forces are unequal.

Then pick:
- A if the velocity is constant for the entire graph.
- B if the velocity is changing for the entire graph.
- C if the graph starts with constant velocity and then changes (equal then became unequal).
- D if the graph starts changing and later becomes constant (unequal then became equal).

Send the graph or a short description and I’ll pick the correct choice and explain.
