To find the final velocity of the car, you can use the kinematic equation:
v = u + at
where: v is the final velocity, u is the initial velocity (in this case, 0 m/s since the car starts from rest), a is the acceleration (2 m/s^2), and t is the time (4 seconds).
Plugging in the values:
v = 0 + (2 m/s^2)(4 s) v = 0 + 8 m/s v = 8 m/s
Therefore, the final velocity of the car after 4 seconds of acceleration is 8 m/s.
