can you please tell me the math and science behind how i would work this out

What if an asteroid impacted Earth during a hurricane?
I was reading about asteroids and just randomly thought if it would be of any significance if one were to hit the earth where a powerful Cat 4 or Cat 5 hurricane was occurring. Would the hurricane affect the asteroid or vice versa?
What are asteroids and what can be the impact of asteroids?
Can someone please tell me what impact an asteroid can cause?
I wish to know this for a project. Thanks in advance. : )
Do asteroids and meteorites leave radioactive traces when they hit earth?
I was arguing with a friend of mine the other day about the Tunguska event in the early 1900′s. He says that a UFO crashed and I said it was a meteorite that exploded in the air. But then he told me that it left a radioactive trace behind. But it got me thinking, would a meteorite impact leave a significant amount of radioactivity.
P.S. I’m not looking for evidence of aliens. I’m only interested in astronomical facts.

What effect would comet bombardment have on the evolution of the primordial atmospheres on terrestrial Planets?
From the abundance of craters on the Moon and Mercury, we know that numerous asteroids and meteoroids struck the inner planets early in the history of our solar system. It is reasonable to suppose that numerous comets also pelted the planets 3.5 to 4.5 billion years ago. There must have been many large icy planetesimals in the Kuiper belt and Oort cloud that collided with each other, producing many large fragments, some that remain out there today. Those that lost a lot of energy during such collisions fell in towards the Sun and some peppered the inner planets with impacts. Much of the water that now exists on Earth, the water that was known to exist on Mars, and evidently the water existed for a brief time on Venus and Mercury were most likely delivered to these planets by these icy fragments.
(a) These impacts probably completely obliterated any atmosphere the planets might have had at that time.
(b) Comets are known to contain lots of organic hydrocarbons, so they probably generated thick atmospheres laden with organic polymers, much like the atmosphere of Titan.
(c) Much of the methane, ammonia and water vapor that marked the early planetary atmospheres also arrived on these fragments. Indeed, methane is broken down by ultraviolet light and hydrogen and nitrogen are released. The hydrogen usually escapes from terrestrial planets but the nitrogen remains in the atmosphere.
(d) They probably punched holes in the crusts of the planets causing natural gas trapped in the crust to be released.
(e) None of the above are likely.
