Final answer:
The acceleration of the mobile clinic en route to the community is 0.022 m/s².
Step-by-step explanation:
To determine the acceleration of the mobile clinic en route to the community, we can use the equation:
a = \frac{{v - u}}{{t}}
Where a is the acceleration, v is the final velocity, u is the initial velocity, and t is the time taken.
In this case, the clinic's initial velocity is 0 m/s and its final velocity is 20 m/s. The time taken to cover the 800-meter distance is 15 minutes, which is equivalent to 900 seconds. Using the equation, we have:
a = \frac{{20 - 0}}{{900}}
Simplifying the equation gives us:
a = 0.022 \, \text{{m/s}}^2
Therefore, the acceleration of the mobile clinic en route to the community is 0.022 m/s².
