Earth is rotating about the Sun in our solar system. The distance between the Earth and Sun is 1.5 × 1011m. Consider the impact of an asteroid of mass 8.9 ×1015 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 × 1024 kg and RE = 6.38 ×106 m, respectively. Assume that the axial and orbital axis of rotations are parallel to each other. (a) Calculate the axial and total angular momentum of the Earth. (b) What is the change in the angular velocity of the Earth due to the collision?
