The velocity at 20 km is .6666 km/s, the velocity at 30 km is .75 km/s. The
difference is .0833 km/s over 10 seconds, which would be .00833 km/s*s =
..00833 km/s^2.

Have fun!

&gt; question: what is the acceleration between 20s and 30s?
&gt; answer: isn't it 0.006 km/s^2 ?
&gt; My daughter insists that it is 0.8 km/s^2
