At least to me, this turned into an interesting math question. All jokes aside.
With any level of certainty, can the angles of scratches on the outermost edge of a wheel of known diameter be used to calculate the height of a curb, which the wheel struck at low velocity?
The wheel didn't strike the curb head on, but rather scraped against the curb while approaching (So, imagine rolling forwards or backwards beside the curb and then attacking it at an angle less than perpendicular).
It comes to mind that the type of curb is unknown, but suspected to be either semi-circular or perpendicular to the ground.
