Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0 km and a mass of 2.5*10^14 kg hits the earth with an impact speed of 4.0*10^4 m/s.
Part A: What is the earth's recoil speed after such a collision? Assume that the mass of the earth is 5.98*10^24 kg. (Use a reference frame in which the earth was initially at rest.)
Part B: What percentage is this of the earth's speed around the sun? Assume that the orbit of the earth is a circle with the radius of 1.5*10^11 m.

One of the main contributing factors to the extinction of the dinosaurs 65 million years ago was a large comet or asteroid that struck the earth. It threw up so much dust that the sun was blocked for a period of many months. Suppose the asteroid had a mass of 4.0x10e13 and hit the earth (mass = 6x10e24 kg) with an impact speed of 4.0x10e4 m/s. What would be the earth's recoil speed after such a collision? (Use a reference...

A comet is deflected by the planet Jupiter into an orbit that puts it on a collision course with Earth. When the comet is 2.00 x 10km from Earth, it is headed directly toward Earth with a speed of 30.0 km/s. What will be the speed of the comet just before it hits Earth's atmosphere at a distance of 6.40 x 10 km from the center of the Earth? The mass of Earth is 5.97 x 10 kg. (a) 31.9...

1. [12 points] Compelling evidence for the asteroid impact 65 million years ago which triggered the extinction of the dinosaurs was discovery of a thin Iridium-rich clay layer in sediments all around the world. A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...

Halley's comet, which passes around the Sun every 76 years, has an elliptical orbit. When closest to the Sun (perihelion) it is at a distance of 8.823×10^10m and moves with a speed of 54.6km/s. When farthest from the Sun (aphelion) it is at a distance of 6.152×10^12mand moves with a speed of 783m/s. Find the angular momentum of Halley's comet at perihelion. (Take the mass of Halley's comet to be 9.8×10^14kg.) Express your answer using two significant figures. Lp Lp =...
