Question

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."

Answer 1

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.

Answer 2

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.
