About 65 million years ago a 10-km-diameter 2×1015kg meteorite traveling at about 10 km/s crashed into what is now the Gulf of Mexico. The impact produced a cloud of debris that darkened Earth and led to the extinction of the dinosaurs.
PART A: Decide the speed Earth gained as a result of this impact. The mass of Earth is 5.98×1024kg.
PART B: Discover the average force that the meteorite exerted on Earth through the collision. Suppose the stopping distance to be 1400m
