Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.
Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.
The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.

The net charge of the asteroid is
with a negative sign since it is a net negative charge.
The charge of one electron is
In order to find what is the excess of electrons on the asteroid, we must simply divide the net charge in excess on the asteroid by the charge of a single electron, and we find:
