I'm pretty sure that's going to depend on the vehicle's mass. I'm sitting here
performing a gedanken experiment right now, with a house fly and a Mercedes
both hitting the same brick wall.
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
no

If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.
no
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
Yes. You are always at fault when you hit a stationary object.
Possibly if the boulder was in the roadway, but if it was actually on your property then they are responsbile for hitting a stationary object.
WHAT THE SPEED OF STATIONARY OBJECT?
Impact; collision; crash; accident
Stationary object refers to an object that is not moving
true
The stationary object is known as a frame of reference. The earth is a common frame of reference for humans.
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
The forces acting on a stationary object are:PushPullGravity
In the frame of reference in which the object is stationary, its speed is zero. (Actually, that's kind of a definition of "stationary".)
It can be.
