An athlete is training on a 100 m long linear track. His motion is described by the graph of his position vs. time, below. 

*Review the photo for reference.*

For each segment of the graph, find the magnitude and direction of the athlete's velocity.

 What are the magnitude and direction of the athlete's average velocity over the entire 60 s interval?

 

An athlete is training on a 100 m long linear track. His motion is described by the graph of his position vs. time, shown below. **Graph Description:** - The vertical axis represents position, \( x \) in meters (m), ranging from 0 to 100 m. - The horizontal axis represents time, \( t \) in seconds (s), ranging from 0 to 60 s. - Four segments are labeled: A, B, C, and D. **Segments:** - **A**: Position increases from 0 m to 40 m from 0 to 10 seconds. - **B**: Position increases from 40 m to 60 m from 10 to 30 seconds. - **C**: Position decreases from 60 m to 40 m from 30 to 40 seconds. - **D**: Position increases from 40 m to 100 m from 40 to 60 seconds. **Questions:** (a) For each segment of the graph, find the magnitude and direction of the athlete's velocity. - Magnitude \( V_A \): ________ m/s Direction \( V_A \): [Select] - Magnitude \( V_B \): ________ m/s Direction \( V_B \): [Select] - Magnitude \( V_C \): ________ m/s Direction \( V_C \): [Select] - Magnitude \( V_D \): ________ m/s Direction \( V_D \): [Select] (b) What are the magnitude and direction of the athlete's average velocity over the entire 60 s interval? - Magnitude: ________ m/s Direction: [Select]
