and heading east on Interstate 70 near Hays, Kansas ?
The extended shovel arm is made of hardened refined
steel and the approaching overpass is made of
commercial-grade concrete, reinforced with 1 1/2 inch
steel rebar spaced at 6 inch intervals in a criss-cross
pattern layered at 1 foot vertical spacing.
do you have to be going to slice the bridge in half??
(Assume no effect for headwind and no braking by the
driver...) Extra Credit: Solve for the time and distance
required for the entire rig to come to a complete stop
after hitting the overpass at the speed calculated above.?
Yes, you can neglect friction.
I couldn't solve it either......but who cares;
the pictures are great!

Let Us Do Our Share
The realization that our own strength may be inadequate should never cause us to sink back into inertia.
Never refrain from a good endeavor because the difficulties involved seem insurmountable.
Keep in mind that we have a mighty Helper in the Almighty in all our good endeavors.
Let us do our share; the Almighty will do the restSubject:
