Question

what is the average speed for segment b? 1 m/s 5 m/s 25 m/s 0 m/s

Explanation:

Step1: Recall the formula for average speed

Average speed \( v=\frac{\Delta d}{\Delta t} \), where \( \Delta d \) is the change in distance and \( \Delta t \) is the change in time.

Step2: Analyze Segment B

For Segment B, the distance \( d \) is constant (horizontal line on the distance - time graph). So, \( \Delta d = 0\).

Step3: Calculate average speed for Segment B

Using the formula \( v=\frac{\Delta d}{\Delta t} \), with \( \Delta d = 0\), we get \( v=\frac{0}{\Delta t}=0\).

Answer:

\(0\space m/s\)
