To calculate the average acceleration from two speeds and the time interval between them, you can use the following formula:
Average acceleration = (Final velocity - Initial velocity) / Time interval
Here's a step-by-step guide on how to calculate it:
Determine the initial velocity (v₀), final velocity (v), and the time interval (Δt) between the two speeds. Make sure that the velocities are measured in the same units (e.g., meters per second).
Subtract the initial velocity from the final velocity: (v - v₀).
Divide the result by the time interval: (v - v₀) / Δt.
The resulting value will give you the average acceleration over that time interval.
It's important to note that this formula assumes constant acceleration between the initial and final velocities. If the acceleration is not constant, or if you have more data points available, you may need to use different methods to calculate the average acceleration, such as fitting a curve to the data or using numerical methods like calculus.
