Final answer:
The initial velocity of the car is 0 m/s and the final velocity is 24 m/s.
Step-by-step explanation:
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
