A "relative" question.

[stoffer]

Ok a coffee cup is resting on a horizontal dashboard. Part a asks at what velocity will the cup slide when you navigate a circular right turn. I did this. So, part b, in what direction relative to the dashboard will the cup slide? I presume its to the left but can someone confirm this for me? or am i wrong?

Thanks

The acceleration is a vector quantity. How did you calculate the acceleration?
