Assume that the density of an average asteroid is 3.1 kg/L, and that the craters on...
Part B please (13% Problem 1: The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 5.25 x 102 kg (such an asteroid is about a kilometer across) strikes the Moon at a speed of 14 km/s relative to the Moon 50% Part (a) At what speed, in meters per second, does the Moon recoil after the perfectly inelastic collision? The mass of the Moon is 7.36 x 102 kg 9.986 10...
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...
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).

3questions in total please *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...
Can someone help me with this question and show all work 1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...
2) Planet Velocities and Energy (10 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation V2= GM.[(2/r) - (1/a)] Here Vis the speed of the body in m/s, G is the gravitational constant, M. is the mass of the Sun...
assume mars to be a uniform solid sphere of mass 6.42 x 10^23 kg and radius 3390 km. The length of day on mars is 24 hours and 37 minutes. Relative to its axis of rotation, calculate the planet's (a) angular speed (b) rotational kinetic energy (c) angular momentum

[Extra point]A typical comet contains 1013 kg of water ice. How many comets would be needed to account for the 2 × 1021 kg of water presently found on our planet? If this amount of water accumulated over a period of 0.5 billion years, how frequently must Earth have been struck by comets during that time? Chapter 5 (10) Because of tidal forces, the Moon is in a synchronous orbit around Earth True False (11) Explain how the Moon produces...
