The corpse was tied to a motorcycle and dragged along the asphalt

The idea was just in the air and sooner or later someone had to do it. Like real cowboys on the ranch, they deftly threw a lasso on the offender and dragged him along on a horse.

Only one question haunts – when will the corpse that is being dragged behind a motorcycle along the asphalt be completely erased? After what time will pitiful stumps of legs drag behind a motorcycle if the density of a human body is 940-990 kg / m3, the weight of the corpse is 80 kg, the speed of the motorcycle is 40 km / h, and the asphalt grain is about 1000 microns?
