Matching Numerical $2$: A highway curve of radius $420$ m is designed for traffic moving at a speed of $19\frac{m}{s}.$ For such traffic, match the quantity on the left with the correct value in SI units $($or degrees for angles$)$ on the right. Each value on the right is used only once.

$a_y,$ the vertical acceleration

A$)0$

$a_c,$ the centripetal acceleration

B$)1\mathrm{.}0$

correct banking angle for the road

C$)0\mathrm{.}86$

ratio of normal force to weight

D$)11$

ratio of normal force to net centripetal force

E$)5\mathrm{.}0$
