4. Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1? Convert your answer to megatons of TNT (1 megaton of TNT = 4.18 x 1015 joules).

A relatively small impact crater 20 kilometers in diameter could be made by a comet 2 kilometers in diameter traveling at 25 km/s (2.5×104 m/s ). a) Assume that the comet has a total mass of 4.2×1012 kilograms. What is its total kinetic energy? (Hint: The kinetic energy is equal to 12mv2, where m is the comet's mass and v is its speed. If you use mass in kilograms and velocity in m/s, the answer for kinetic energy will have...

Assume that the density of an average asteroid is 3.1 kg/L, and that the craters on the Moon are roughly 15 times the size of the impacting body. a. What was the diameter of the asteroid that created the 240-km-diameter Clavius crater? D= 16 km Using the density of an average asteroid, calculate the mass of this asteroid. m= *10 15 kg b. Calculate the kinetic energy of this impact if the speed of the asteroid was 22 km/sec relative...

On August 10, 1972, a large meteorite skipped across the atmosphere above the western United States and western Canada, much like a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter than the usual meteorite trail. The meteorite's mass was about 3.8 × 106 kg; it's speed was about 13 km/s. Had it entered the atmosphere vertically, it would have hit Earth's surface with about the same...

Flying Circus of Physics On August 10, 1972, a large meteorite skipped across the atmosphere above the western United States and western Canada, much like a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter than the usual meteorite trail. The meteorite's mass was about 3.9 x 106 kg; it's speed was about 15 km/s....

*Problem 6.66 You stand on a spherical asteroid of uniform density whose mass is 2.5 x 1016 kg and whose radius is 11 km (11 x 103 m). These are typical values for small asteroids, although some asteroids have been found to have much lower average density and are thought to be loose agglomerations of shattered rocks. You want to figure out how fast you have to throw the rock so that it never comes back...

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...

Constants Part A An asteroid with a diameter of 10 km and a mass of 2.60 x1015 kg impacts the earth at a speed of 32.0 km/s, landing in the Pacific Ocean. If 1 ,00 % of the asteroid's kinetic energy goes to boiling the ocean water (assume an initial water temperature of 10.0 °C), what mass of water wil be boiled away by the collision? (For comparison, the mass of water contained in Lake Superior is about 2 x...
