For a short time, the $350-kg$ roller$-$coaster car with passengers is traveling along the spiral track as shown in $($Figure $1)$ at a constant speed such that its position measured from the top of the track has components $r=10m,=(0\mathrm{.}2t)rad,$ and $z=(-0\mathrm{.}3t)m,$ where $t$ is in seconds.

Figure

$1$ of $1$

Determine the magnitudes of the components of force which the track exerts on the car in the $r,,$ and $z$ directions at the instant $t=2s.$ Neglect the size of the car.
