Answer to Question #249024 in Civil and Environmental Engineering for toto

Question

 Vehicles often travel city streets adjacent to parking lanes at 56 kph or faster. At his speed and setting detection through response-initiation time for an alert driver at 2 sec. and f = 0.50, how far must the driver be away from a suddenly opened car door to avoid striking it?

Answer 1

$SSD = V_t+\frac{v^2}{2gf}\\ SSD =56*\frac{2}{18}+\frac{(56*\frac{2}{18})^2}{2*9.81*0.5}\\ SSD=10.16881 m$
