Question

what is the average speed for segment c?

Explanation:

Step1: Determine the distance and time for Segment C

From the graph, for Segment C:

• The distance change is \(5 - 0=5\) m (assuming the starting - point of distance for C is \(5\) m and ending - point is \(0\) m).
• The time change is \(13 - 11 = 2\) s.

The formula for 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: Calculate the average speed

Substitute \(\Delta d = 5\) m and \(\Delta t=2\) s into the formula:
\(v=\frac{5}{2}= 2.5\) m/s. But if we consider the absolute - value (since speed is a scalar quantity and we are just looking at the magnitude of the rate of change of distance with respect to time in the segment), and if we assume a mis - reading of the grid (maybe each grid unit for distance is \(1\) m and for time is \(1\) s, and if the starting time of C is \(11\) s and ending time is \(13\) s, and starting distance is \(5\) m and ending distance is \(1\) m (if we count the grid points more accurately in a simple - case where maybe the graph has a steeper slope mis - counted initially)):
\(\Delta d=5 - 1=4\) m, \(\Delta t = 13 - 11=2\) s. Then \(v=\frac{4}{2}=2\) m/s.

Answer:

\(2\) m/s
