1. The problem statement, all variables and given/known data

A parcel sits on a seat angled θ to the horizontal. The car is travelling along a local radius of curvature of 80m and is travelling 20m/s at the dip. For what value of theta will the parcel not slip?

Will someone check that my force diagram is correct?
Thanks,
cmcd

$$\rho(h)=\rho_0\exp^-\frac{\rho_0g_ph}{p_0}$$
