P$2$: A&B

For this problem, consider a design velocity of $50[$mph$]$ and curves that are designed to provide adequate

Stopping Sight Distance.

Assume that vertical curve design parameter values are the following.

h$\_(1)($driver$\text{'}$s eye$)$

h$\_(2)$ for SSD $($object$)$

h$\_(2)$ for PSD $($object$)$

h$\_($H$)($height of headlights$)$

$\backslash$beta $($angle of headlight$)$

$|$a$|$

t$\_($r$)$

$3\mathrm{.}0[$ft$]$

$1\mathrm{.}0[$ft$]$

$4\mathrm{.}0[$ft$]$

$1\mathrm{.}5[$ft$]$

$1\backslash$deg

$16\mathrm{.}0[$f$($t$)/($sec$^(2))]50[$mph$]$ G$\_(1)=0\mathrm{.}02$ and G$\_(2)=-0\mathrm{.}01.$ What is

the minimum length of curve required to provide adequate Stopping Sight Distance at $40[$mph$]?$ Provide

your answer to the nearest foot, and remember to check your conditions.
