Calculate v = (v + u) / 2. Choose a calculation to find average velocity (v), initial velocity (u) or final velocity (v). Enter two values and the calculator will solve for the third. You can also enter scientific notation in the format 3.45e9, with no spaces between numbers and the exponent indicator, e.
Where:
The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers. The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.
During a 5k race, the velocities of runners are taken at the beginning and end of the 3rd mile. If Runner A is running at 10 mph at the start of the mile and 7.5 mph at the end of it, what is her average velocity?
In this problem the initial velocity is 10 mph and the final velocity is 7.5 mph. Using the formula, we calculate v to be equal to (10+7.5) mph/ 2 giving us 8.75 mph as Runner A’s average velocity.
