Answer: D. 46 m/s Density
A set of equations describe the resultant trajectories when objects move owing to a constant gravitational force under normal Earth-bound conditions.For example Newton’s law of universal gravitation simplifies to F = mg where m is the mass of the body. This assumption is reasonable for objects falling to earth over the relatively short vertical distances of our everyday experience but is …

After 10 seconds a body starting from rest on the equator would have risen only about 1.5 m and be travelling at only about 1.1km/hr almost vertically upwards relative to the surface of the Earth and the Coriolis force on it would still be negligible. After 100 seconds it would still have risen only about 16.5 m and be travelling at about …
