Acceleration in meters per square second. A car begins at rest at a stop sign, it accelerates 25m/s over a time of 8.6sec
V = a*t.

To find the acceleration, we can use the equation:
acceleration (a) = (change in velocity)/(time taken)
Here, the change in velocity is 25 m/s and the time taken is 8.6 seconds.
So, the acceleration is:
a = 25 m/s / 8.6 sec
a ≈ 2.91 m/s²
Therefore, the acceleration of the car is approximately 2.91 meters per square second.
To calculate the acceleration, we can use the formula:
acceleration (a) = (final velocity - initial velocity) / time
In this example, the initial velocity (u) is 0 m/s (since the car begins at rest) and the final velocity (v) is 25 m/s. The time (t) is given as 8.6 seconds.
Plugging these values into the formula, we get:
a = (25 m/s - 0 m/s) / 8.6 s
Simplifying the equation, we have:
a = 25 m/s / 8.6 s
Therefore, the acceleration of the car is approximately 2.906 m/s^2 (meters per square second).
