A car traveling in a straight line has a velocity

of 3.7 m/s at some instant. After 7.99 s, its
velocity is 12.2 m/s.
What is its average acceleration in this time
interval?
Answer in units of m/s

So average acceleration is just the 'slope' of the velocity vs time graph..

The equation would be (Vf - V0)/t = average acceleration...

(12.2-3.7)/7.99 = 1.06 m/s^2 because the units are (m/s)/s
