Why might a wine glass survive a fall onto a carpeted floor but not onto a concrete floor? 1. since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact. 2. the decrease of velocity of the wine in the carpet is more than that in the concrete. 3. the decrease of velocity of the wine glass in the carpet is less than that in the concrete. 4. the decrease of momentum of the wine glass in the carpet is less than that in the concrete. 5. the decrease of momentum of the wine glass in the carpet is more than that in the concrete?

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.
