The initial velocity of the car is 0 m/s and the final velocity is 24 m/s.

The initial velocity of the car can be calculated using the equation:

final velocity = initial velocity + (acceleration x time)

Since the car started from rest, the initial velocity is 0 m/s. Plugging in the values, we get:

24 m/s = 0 m/s + (acceleration x 4s)

Solving for acceleration, we find:

acceleration = 6 m/s²

Now we can calculate the final velocity using the equation:

final velocity = initial velocity + (acceleration x time)

Plugging in the values, we get:

final velocity = 0 m/s + (6 m/s² x 4s)

final velocity = 24 m/s
