1. Convert Units:
* Velocity: 54 mph needs to be converted to meters per second (m/s).
* 1 mile = 1609.34 meters
* 1 hour = 3600 seconds
* 54 mph * (1609.34 m/mile) / (3600 s/hour) ≈ 24.14 m/s
* Time: 5 seconds is already in the correct unit.
2. Calculate Acceleration:
* Acceleration is the change in velocity over time.
* Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t)
* Since the car starts from rest, the initial velocity (u) is 0 m/s.
* a = (24.14 m/s - 0 m/s) / 5 s
* a = 4.83 m/s²
Therefore, the acceleration of the driver is approximately 4.83 m/s².
