Answer:

5.27 m/s²

Explanation:

Given data

  • Initial velocity (v₀): 0 m/s (rest)
  • Final velocity (vf): 42.3 m/s
  • Elapsed time (t): 8.02 s
  • Acceleration (a): ?

We can determine the acceleration of the car using the following kinematic expression.

a = Δv / t

a = vf - v₀ / t

a = (42.3 m/s - 0 m/s) / 8.02 s

a = 5.27 m/s²

The acceleration of the car is 5.27 m/s².
