FINAL ANSWER:
0.6 meters per second squared
Step-by-step explanation:
To calculate the skateboarder's acceleration, you can use the following formula:
Acceleration (a) = (Change in Velocity) / (Time)
In this case, the change in velocity is from 4 m/s to 10 m/s, which is:
Change in Velocity = 10 m/s - 4 m/s = 6 m/s
The time taken for this change is 10 seconds.
Now, plug these values into the formula:
Acceleration (a) = (6 m/s) / (10 s)
Acceleration (a) = 0.6 m/s²
So, the skateboarder's acceleration is 0.6 meters per second squared (m/s²).
