Solving for Average Acceleration: An Automotive Example

Click For Summary
To calculate the average acceleration of a car traveling in a straight line, the formula used is \(\bar{a} = \frac{\Delta v}{\Delta t}\). Given the initial velocity of +5.0 m/s and a final velocity of +8.0 m/s over a time interval of 4.0 seconds, the change in velocity (\(\Delta v\)) is +3.0 m/s. Dividing this change by the time interval (\(\Delta t\)) of 4.0 seconds results in an average acceleration of +0.75 m/s². This calculation demonstrates the straightforward application of the average acceleration formula in automotive scenarios.

was wondering which formula I would use to solve this equation...

a car traveling in a straight line has a velocity of +5.0m/s at some instant.
After 4.0seconds, it velocity is +8.0m/s. What is it average acceleration in this time interval?
