Pablo is running sprints. At 10 seconds, his speed is 2 m/s. At 20 seconds, his speed is 4 m/s. What is his acceleration?
a = change in speed / change in time = (4 - 2) /(20-10) = 2/10 = 0.2 m/s^2
Thank you Mister Damon
You are welcome.
To find Pablo's acceleration, we can use the formula for acceleration:
Acceleration = (Final Velocity - Initial Velocity) / Time
In this case, the initial velocity is 2 m/s at 10 seconds, and the final velocity is 4 m/s at 20 seconds. The time interval is 20 seconds - 10 seconds = 10 seconds.
So, the acceleration is:
Acceleration = (4 m/s - 2 m/s) / 10 s = 2 m/s / 10 s = 0.2 m/s²
Therefore, Pablo's acceleration is 0.2 m/s².
