"two marks on the bridge" were made on the rub rail by the wheels
as the car went over--the right front wheel first, then the left. .
This was because of the angle of the bridge to the road.) The hor~
izontal distance the automobile hurtied from the bridge, then, was =.

spector Kennedy, who was generous enough to allow for a ten per

But that isn't all there is to it. When it left the bridge, the car trav-

it would have traveled otherwise before hitting the bottom of the cond, Had
C . this further distance been only three feet, the speed must be adjusted to about

can fix this as the minimum speed thusly, that conjecture being accepted:
; The vertical drop was eight feet, Kr. Farrar said, but the photogrenh of
the bridge on page 121 of The Inquest at slack tide forces the canclusion that
this was only to the weiter. There wes another shy six feet to go through water,
totalling 1: feet, probably less a few inches. Now then, from ose of tne first
laws we learn in physics, the Law of Falling Bodies, we know thzt during the
first second of fall the vertical distance traveled is 16 feet (if wind resis:

.Mr. Kennedy stated that at no time after he tumed onto the
unpaved Dike Road had he realized he had made a "wrong turn” (un-
til just the moment before going off the bridge). Yet, he admit-
ted he knéw the road from the -cottage (where the cook-out was held)
to the ferry was paved. He also admitted having become “generally
aware sometime" while on Dike Road that it was unpaved. Accord-
ingly, therefore, he had to know that he was not on the way to the
ferry, which he said was his immediate destination. ; -
See further discussion concerning both Dike Road and the
bridge in a later section.
