Final answer:
To find the net force acting on a cyclist, Newton's second law is applied. The force is the product of mass and acceleration. Without the mass of the cyclist, the net force cannot be determined, even though a specific value is suggested in the information provided.
Step-by-step explanation:
The question pertains to finding the magnitude of the net force acting on a cyclist. To solve for the net force, Newton's second law of motion, which states that F = ma (force equals mass times acceleration), can be utilized. Given a cyclist with an acceleration and the mass of the cyclist, we can calculate the net force. However, without the mass of the cyclist, the net force cannot be accurately determined from the data provided. From the information given, it appears that a specific net force value (661 N) was calculated, presumably taking into account the mass of the cyclist and the acceleration.
Considering that a net force of 661 N is mentioned, and assuming it is correct, it would indicate that the cyclist is experiencing a positive net force at the finish line, causing acceleration. However, to confirm this, one would need explicit mass and acceleration values directly from the problem's text. Since those are not provided in the question, the net force acting on the cyclist at the finish line cannot be definitively answered without additional information.
