Question

Imagine a cart moving with constant velocity over a piece of paper. If the cart makes a mark directly beneath it on the paper at a regular time interval, in this case every 0.1 s, the marks would look like diagram A above. This is known as a “ticker tape” diagram of motion.
In the ticker tape diagram above, where does the cart have positive acceleration?
Where does it have negative acceleration?
Explain what features in diagram B you interpret as positive and negative acceleration.
If the dots were spaced widely apart in the diagram, then what could you infer about the speed of the cart?
