A Backhoe weighting 8 tons is on top of a flat-bed trailer and heading west on a highway / roadway.?

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 crisscross pattern layered at 1 foot spacing. Solve: When the shovel arm strikes the overpass, what is the velocity of the vehicle (how fast is it travelling) 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.

as a truck driver i can assure you that this is impossible as there is not a truck that can move the trailer fast enough to completely sever the overpass as the tires would first fail, then the trailer would break apart. the stop would be in less than 8 seconds as the baskhoe would then be blocking the traffic flow west bound underneath the overpass.
