Final answer:
To find average acceleration, subtract the initial velocity from the final velocity, subtract the initial time from the final time, and divide the change in velocity by the change in time.
Step-by-step explanation:
To find average acceleration, you need to determine the change in velocity and the change in time. First, subtract the initial velocity from the final velocity to find the change in velocity. Then, subtract the initial time from the final time to find the change in time. Finally, divide the change in velocity by the change in time to calculate the average acceleration.
