it takes 14 seconds for a runner to go from 5m/s to 19m/s?
how do you calucate acceleration
To calculate acceleration, you need to use the formula:
Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)
In this case, the runner's initial velocity (u) is 5 m/s, the final velocity (v) is 19 m/s, and the time taken (t) is 14 seconds.
Substituting the values into the formula, you get:
Acceleration (a) = (19 m/s - 5 m/s) / 14 s
Simplifying the equation further:
Acceleration (a) = 14 m/s / 14 s
The unit of time (s) cancels out, leaving us with the final answer:
Acceleration (a) = 1 m/s²
Therefore, the runner's acceleration is 1 meter per second squared.
