o kousicek - tadyk

No a kdyby nas nahodou trefila, tak by to dopadlo asi tak nejak: (tu mozno libovolne katastroficke scenare spocitati )

Your Inputs:
Distance from Impact: 1000.00 km = 621.00 miles
Projectile Diameter: 30.00 m = 98.40 ft = 0.02 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 17.00 km/s = 10.56 miles/s
Impact Angle: 90 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock

Energy:
Energy before atmospheric entry: 1.63 x 1016 Joules = 3.90 MegaTons TNT
The average interval between impacts of this size somewhere on Earth is 314.0 years

Atmospheric Entry:
The projectile begins to breakup at an altitude of 14100 meters = 46100 ft
The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 10.8 km/s = 6.7 miles/s
The impact energy is 6.58 x 1015 Joules = 1.57 MegaTons.
The broken projectile fragments strike the ground in an ellipse of dimension 0.151 km by 0.151 km

Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the Earth's rotation period or the tilt of its axis.
The impact does not shift the Earth's orbit noticeably.

Crater Dimensions:
What does this mean?

Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed.

Transient Crater Diameter: 875 m = 2870 ft
Transient Crater Depth: 309 m = 1010 ft

Final Crater Diameter: 1090 m = 3590 ft
Final Crater Depth: 233 m = 765 ft

The crater formed is a simple crater

The floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 108 m = 355 ft.
At this impact velocity ( < 12 km/s), little shock melting of the target occurs.

Thermal Radiation:
What does this mean?

At this impact velocity ( < 15 km/s), little vaporization occurs; no fireball is created, therefore, there is no thermal radiation damage.

Seismic Effects:
What does this mean?

The major seismic shaking will arrive at approximately 200 seconds.
Richter Scale Magnitude: 4.7
Mercalli Scale Intensity at a distance of 1000 km:

Nothing would be felt. However, seismic equipment may still detect the shaking.

Ejecta:
What does this mean?

Most ejecta is blocked by Earth's atmosphere

Air Blast:
What does this mean?

The air blast will arrive at approximately 3030 seconds.
Peak Overpressure: 63.3 Pa = 0.000633 bars = 0.00899 psi
Max wind velocity: 0.149 m/s = 0.334 mph
Sound Intensity: 36 dB (Easily Heard)

Ehm, teda pokud by byla trebas ze zeleza , neb kdyby byla ze sutru tak by na zem ani nedopadla
