Ramon and sally are observing a toy car speed up as it goes around a circular track. ramon says, "the car's speeding up, so there must be a net force parallel to the track." "i don't think so," replies sally. "it's moving in a circle, and that requires centripetal acceleration. the net force has to point to the center of the circle."

Final answer:

Ramon and Sally both have valid points. The car's speed increasing indicates the presence of a net force, but the circular path requires a centripetal force towards the center.

Step-by-step explanation:

Both Ramon and Sally make valid points about the observations they are making. Ramon is correct in stating that the car is speeding up, which indicates the presence of a net force. However, Sally is also correct in saying that for the car to move in a circular path, there must be a centripetal force pointing towards the center of the circle. The centripetal force is responsible for producing the centripetal acceleration that keeps the car in its circular path.

The changing speed demonstrates the nearness of an increasing speed; this centripetal quickening is of enduring with significance and coordinated in any regard cases toward the hub of the pivot. This increasing speed is, thus, created by utilizing a centripetal anxiety that is furthermore reliable in significance and coordinated toward the hub of revolution. contained in regards to revolution around a settled hub of a firm build that is not irrelevantly little in contrast with the span of the course, each and every molecule of the constitution portrays a uniform around activity with the equivalent rakish speed, yet with speed and increasing speed different with the range with comprehend to the hub.
