Question

what would the motion graph look like for a bicyclist who gets a flat tire in the middle of a race?

Explanation:

Step1: Analyze motion before flat - tire

Before getting a flat tire, the bicyclist is moving forward, so the distance - time graph shows an increase in distance with time.

Step2: Analyze motion after flat - tire

Once the bicyclist gets a flat tire, they stop moving. So the distance remains constant while time continues to pass.

Answer:

A. The graph with an initial upward - sloping line (representing motion) followed by a horizontal line (representing no motion).
