Solution

Solution Steps

Step 1: Analyze the motion between D and E

Point D is at a position of approximately 2 m at t = 7 s. Point E is at a position of approximately 3 m at t = 9 s.

Step 2: Calculate the average velocity

The average velocity is given by the change in position divided by the change in time: Average velocity = (Position at E - Position at D) / (Time at E - Time at D) Average velocity = (3 m - 2 m) / (9 s - 7 s) Average velocity = 1 m / 2 s Average velocity = 0.5 m/s

Step 3: Determine the sign of the average velocity

Since the average velocity is positive (0.5 m/s), the direction of the average velocity is positive.
