Answer

9.7g

Work Step by Step

We have the radius of the turn and the speed at which it was made so we can find the centripetal acceleration since $a_{c} = v^2/r$. First we convert 96.6km/h to m/s and find that it is 26.8m/s and we have the radius as 7.6m. Therefore, the acceleration is 94.7 $m/s^2$. Then to find this in terms of g, we divide this by g, which is 9.8 and we get 9.7.
