The new horizons spacecraft (mass 478 kg) was launched from earth in 2006 and flew past pluto in 2015. what minimum amount of work has to be done on a spacecraft of this mass to send it from the earth's surface to infinitely far away from the earth? neglect air resistance and the gravitational effects of the sun, moon, and other planets.

Apossible explanation for a set of facts that can be tested by further investigation is called

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
