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 2.0 km and a mass of 1.1 ×1013 kg hits the earth (6.0×1024 kg) with an impact speed of 4.5 ×104 m/s. a. What is the earth’s recoil speed after such a collision? (Use a...

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...

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...

014 (part 1 of 2) 10.0 points Ever since it was learned that an aster- oid hit the earth 65 million years ago and destroyed most life-forms, including the di- nosaurs, observations of new comets are fol- lowed with great interest! Suppose a new comet is found orbiting the sun as it is pass- ing its point of closest approach at a distance Tmin 0.658 AU (1 AU-semimajor axis (average radius) of the Earth's orbit.) Careful studies determine that its...

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...
