Q. A plane diving with a constant speed at an angle of 41.7 degrees with the vertical, releases a package at an altitude of 540. m. The package hits the ground 3.59 s after the release. How far horizontally does the package travel?
Q. The Earth can be approximated as a sphere of uniform density, rotating on its axis once a day. The mass of the Earth is 5.97×1024 kg, the radius of the Earth is 6.38×106 m, and the period of rotation for the Earth is 24.0 hrs.
What is the moment of inertia of the Earth? Use the uniform-sphere approximation described in the introduction.
