Earth is rotating about the Sun in our solar system. The distance between the Earth and Sun is 1.5 x 10"m. Consider the impact of an asteroid of mass 8.9 x1015 kg and a speed of 90,000 km/h with respect to the Earth's surface. The asteroid strikes the Earth at the equator as shown in Figure. Consider the mass and radius of the Earth are ME = 5.97 x 10²4 kg and RE = 6.38 x10 m, respectively. Assume that the axial and orbital axis of rotations are parallel to each other. Earth North Pole
