The egg breaks. But when the egg strikes the sagging sheet, impact time is long and the force correspondingly small. Doing this makes a nice demonstration of impulsemomentum. The large momentum of the spurting water is met by a recoil that makes the hose difficult to hold, just as a shotgun is difficult to hold when it fires birdshot. The gun would recoil with a speed ten times the muzzle velocity.
Impulse is force x time.
The forces are equal and opposite, by Newton's third law, and the times are the same, so the impulses are equal and opposite. The momentum of recoil of the world is 10 units of momentum. Again, this is not apparent because the mass of the earth is so enormous that its recoil velocity is imperceptible. The momentum of the falling apple is transferred to the earth. Interestingly enough, when the apple is released, both the earth and the apple move toward each other with equal and oppositely directed momenta.
