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
5.0km and a mass of 2.5
a)
Ma (asteroid)= 2.5*10^14 kg
Da (diameter/asteroid)= 5000m
Va =4.0*10^4 m/s
Me (earth)= 5.98*10^24 kg
Ve=0
because this is an elastic collision meaning it doesn't bounce off.
This is your equation: Ma*Va= (Ma+Me) Vf
solving for Vf we get
Vf=(Ma*Va)/(Ma+Me)
2.5*10^14*4*10^4/2.5*10^14+5.98*10^24
= 10^19/10^14(2.5+ 5.98*10^10)
= 10^19/5.98*10^23
= 1.67*10^-4 m/sec
b) 1.67*10^-4/1.5*10^11
=1.11*10^-15

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 2.5×1014 kg hits the earth with an impact speed of 3.0×104 m/s . What is the earth's recoil speed after such a collision? Assume that the mass of the...
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?

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...
please show work/formulas and answers so I can understand where the numbers and such are coming from. thanks!

21.The asteroid impact 65 million years ago in Yucatan, Mexico that caused the dinosaurs to become extinct caused this kind of damage in Hell Creek, Montana: a.electromagnetic evacuation of oxygen from the atmosphere! b.megatsunami waves in Montana! c.nuclear explosion in the atmosphere! d.Hell Creek was plunged into the center of the Earth!
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...
FISCAL POLICY IN THEORY: March, 2020: we are on the verge of Congress and the President passing legislation that will empower the federal government to spend an unprecedented amount of EXTRA money not seen since World War 2 ---- in order to address the pandemic but also to help cushion the blow financially of perhaps ten or twenty million Americans --- or more --- losing their jobs, and thus suffering a drop in income. The scale of the 2020 recession...
