Question

select the correct answer.
sally is training for the 1,000 - meter running race at her school. her goal is to place third or better. how can sally determine if she is making progress toward her goal?
○ a. she can monitor her practice run times to see if they are decreasing.
○ b. she can watch a video of her running to uncover any deficiencies.
○ c. she can draw a diagram that depicts the forces acting on her legs.
○ d. she can complete an energy analysis to compare her output to her input.

Explanation:

If Sally's practice run times are decreasing, it indicates she is getting faster. Since the goal is to place third or better in a running race (where faster times are better), monitoring decreasing run - times shows progress. Watching a video (B) might show form issues but not direct progress towards the goal. Drawing force diagrams (C) and energy analysis (D) are more technical and not as directly related to the goal of improving race placement as monitoring run times.

Answer:

A. She can monitor her practice run times to see if they are decreasing.
