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?
