This question concerns the linear speed of the Great Pyramid in Egypt relative to the centre of the Earth. The angle between the Earth's axis of rotation and the radial line joining the centre of the Earth to the Great Pyramid is 60.0°. Given that the radius of the Earth is 6.38 x 106 m and that 1 sidereal day = 8.62 x 104 s, what is the linear speed of the Great Pyramid relative to the centre of the Earth due to the Earth's daily rotation? Give your answer in scientific notation, correct to 3 significant figures.
