Answer:
The average acceleration is 0.6 m/s²
Step-by-step explanation:
Given that,
Velocity (m/s) = 5, 10, 15 and 20
Time (sec) = 5, 10, 15 and 20
We know that,
The velocity and time graph shows the acceleration.
We need to calculate the average acceleration
Using formula of average acceleration

Where,
= final velocity
= initial velocity
a = acceleration
t = time
Put the value into the formula


Hence, The average acceleration is 0.6 m/s²
