A NASA satellite has just observed an asteroid that is on a collision course with the Earth. The asteroid has an estimated mass, based on its size, of 5 X 10^9 Kg. it is approaching the Earth on a head-on course with a velocity of 600 m/s relative to the Earth and is now 5.0 x 10^6 km away. The average force of air resistance is 3.7 x 10^11 N as the asteroid moves 300 km through the atmosphere. With what speed will it hit the Earth's surface (assume the mass of the asteroid stays constant as it moves through the atmosphere)?

Thank you.

Solution Summary

The solution provides two different methods of determining the speed of an asteroid when it impacts with Earth, given the asteroid's dimensions. It explains the idea behind the calculations clearly as well, first in the answer space and then in further detail in an attachment.

5. Consider a spherical asteroid with a radius of 12 km and a mass of 3.45 x 10 to the fifteenth power kg. (a) What is the acceleration of gravity on the surface of this asteroid? (b) Suppose the asteroid spins about an axis through its center, like the Earth, with an angular speed w. What is the greatest value w can have befor

A newly discovered faint asteroid and Mars are observed at opposition. Mars is observed to be 100 million times brighter than the asteroid. Assume Mars and the asteroid are 1.5 and 3.0 AU from the Sun respectively.
(a) Estimate the radius of the asteroid if it has an albedo of 16%.
(b) Estimate the radius of the asteroid if it

On Wednesday 9th of November 2011 asteroid 2005 YU55 passed by the Earth at a distance of 323,469 km, which is closer than the Moon. There was no possibility of it hitting the Earth - this time. Just for interests sake, assume there was an asteroid heading for Earth, and it was necessary to blow it up, so that instead of a large

See attached graphic.
A small asteroid is moving in a circular orbit of radius R_0 about the sun. This asteroid is suddenly struck by another asteroid. (We won't worry about what happens to the second asteroid, and we'll assume that the first asteroid does not acquire a high enough velocity to escape from the sun's gravity).

5. Zero, a hypothetical planet, has a mass of 4.0 x 10^23 kg, a radius of 3.0 x 10^6 m, and no atmosphere. A 15 kg space probe is to be launched vertically from its surface.
(a) If the probe is launched with an initial kinetic energy of 5.0 x 10^7 J, what will be its kinetic energy when it is 4.0 x 10^6 m from the center of Z

[1] What concepts would you use to describe the asteroid's motion?
[2] If the asteroid is moving at a constant speed in its orbit, does this also mean it is moving at a constant velocity? Explain your answer.
[3] Based on your answer above, is the asteroid accelerating? Explain.
[4] What force acts to hold this massive object

A spaceship moves away from Earth at a speed 0.874c and fires a shuttle craft that then moves in a forward direction at 0.21c relative to the ship. The pilot of the shuttle launches a probe forward at a speed of 0.412c relative to the shuttle.
Determine the speed of the shuttle relative to Earth. Answer in units of c.

Two meteoroids are heading for earth. Their speeds as they cross the moon's orbit are 2.0 km/s.
(A) The first meteoroid is heading straight for earth. What is its speed of impact? Make sure your answer is in km/s.
(B) The second mi
