Answer:
The average velocity is -7.675 m/s
Step-by-step explanation:
Given;
initial velocity, u = 0 m/s
final velocity, v = -15.35 m/s
Based on the follow up state " In general, to find the average of any 2 things, you add them together and divide by how many things there are", the average velocity will be calculate as ;
Sum of the velocities = 0 m/s + (-15.35 m/s) = -15.35 m/s
Number of velocites = 2
AVERAGE VELOCITY = (-15.35 m/s) / (2)
AVERAGE VELOCITY = -7.675 m/s
