Answer:
Average velocity = -3.84 m/s
Explanation:
Given the following data;
Initial velocity = 0 m/s
Final velocity = -7.68 m/s
To find the average velocity;
Average velocity = (U + V)/2
Average velocity = (0 + [-7.68])/2
Average velocity = -7.68/2
Average velocity = -3.84 m/s
Therefore, the average velocity of the rock is -3.84 meters per seconds.
