In 2021, three seismic events were recorded on Mars by the InSight lander due to meteor impacts. These shock waves provide valuable data about the interior of Mars, and also information on the frequency of impact of these objects with Mars. a) Calculate the momentum change of Mars due to this impact - assume the meteor struck Mars with a mass and speed similar to the Chelyabinsk meteor that exploded in the skies of Russia in 2013. Use a mass of 1.3x107 kg and a speed of 19,000 m/s for the meteor, relative to Mars. Mars has a mass of 6.4x1023 kg. How fast is Mars moving after impact
