3. experiment: check that there are no fans on the cart. on the description tab, set the initial velocity of the cart to 2.0 m/s. select the bar chart tab, and click play. what do you notice about the velocity of the cart?
Answer
Brief Explanations:
In the absence of external horizontal forces (no fans means no additional horizontal - acting forces), according to Newton's first law, an object in motion will maintain its state of motion. So the cart should move with a constant velocity.
Answer:
The velocity of the cart remains constant at 2.0 m/s.
