A=vf-vi÷t
The equation you mentioned, A = (vf - vi) / t, represents the formula for acceleration. In this equation, A represents the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time taken.
To calculate the acceleration using this formula, follow these steps:
1. Determine the values of vf, vi, and t. Make sure to use consistent units for velocity (such as meters per second) and time (such as seconds).
2. Subtract the initial velocity (vi) from the final velocity (vf).
3. Divide the difference by the time (t).
Here's an example to illustrate the calculation:
Let's say the final velocity (vf) is 30 meters per second, the initial velocity (vi) is 10 meters per second, and the time (t) is 5 seconds.
A = (vf - vi) / t
A = (30 - 10) / 5
A = 20 / 5
A = 4 meters per second squared
Therefore, the acceleration in this example is 4 meters per second squared.
