Understanding the Concepts
* Average Acceleration: The change in velocity over a period of time.
* Initial Velocity (v₀): The dragster starts from rest, so v₀ = 0 m/s.
* Final Velocity (v): The dragster reaches a final speed of 210 m/s.
* Time (t): The time taken to cover the distance is 3.8 seconds.
Formula
Average Acceleration (a) = (Final Velocity (v) - Initial Velocity (v₀)) / Time (t)
Calculation
1. Plug in the values:
a = (210 m/s - 0 m/s) / 3.8 s
2. Calculate:
a = 210 m/s / 3.8 s
a = 55.26 m/s² (approximately)
Answer
The average acceleration of the dragster is approximately 55.26 m/s².
