## Homework Statement

The position of an object moving along the x-axis is given by x=a+bt^2, where a=8.5m,b=2.5 ms^-2, and t is measured in seconds. what is the average velocity between t=2.0 s and t= 4.0 s

## Homework Equations

as we know, Vavg = xf-xi / tf-ti (f= final position and time and i= initial position and time)

## The Attempt at a Solution

Where to put the values because we have the values of t but there are no values of x
