9. A drag racer accelerated from 0 m/s to 200 m/s in 5 s. What was the acceleration?
To calculate the acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) / time
acceleration = (200 m/s - 0 m/s) / 5 s
acceleration = 200 m/s / 5 s
acceleration = 40 m/s^2
Therefore, the acceleration of the drag racer was 40 m/s^2.
