To find the average velocity of the car, we divide the total displacement by the total time taken. The average velocity formula is:

Average velocity = Total displacement / Total time

In this case, the car travels a total distance of 560 meters in 8 seconds. Therefore:

Average velocity = 560 meters / 8 seconds Average velocity = 70 meters per second

So, the average velocity of the car is 70 m/s.

To find the final velocity of the car, we need to use the kinematic equation that relates initial velocity (u), final velocity (v), acceleration (a), and time (t):

v = u + at

Since the car starts from rest (u = 0) and has constant acceleration, we can rearrange the equation to solve for the final velocity:

v = u + at v = 0 + a * t v = a * t

Given that the car travels for 8 seconds, we need to determine the acceleration first. We can use the equation that relates displacement (s), initial velocity (u), final velocity (v), and acceleration (a):

s = ut + (1/2) * a * t^2

Plugging in the values we have:

560 = 0 * 8 + (1/2) * a * (8^2) 560 = 32a a = 560 / 32 a ≈ 17.5 m/s^2

Now, we can find the final velocity using the equation v = a * t:

v = a * t v = 17.5 * 8 v = 140 m/s

Therefore, the final velocity of the car is 140 m/s.
