A satellite in orbit around the earth is at an altitude of 107 percent of the earth's radius. Rounding off our old friend "g" to ten meters per second squared, what is the acceleration due to earth's gravity at the satellite? Your answer should be in meters per second squared, but do not put the unit, just the number.
A certain spherical planet is made up of two types of material: in the inner core (from the center to radius r = 2R), the mass density is p1; in the outer core (r = 2R to r= 5R), the mass density is p2 = 1/2 p1. Using Gauss’s law, determine the gravitational field at r = 3R in terms of the variables provided.

Using Figure 13.9, carefull sketch a free body diagram for the case of a simple pendulum hanging at latitude lambda, labeling all forces acting on the point mass,m. Set up the equations of motion for equilibrium, setting one coordinate in the direction of the centripetal accleration (toward P in the diagram), the other perpendicular to that. Show that the deflection angle , defined as the angle between the pendulum string and the radial direction toward the center of Earth, is given by the expression below. What is the deflection angle at latitude 45 degrees? Assume that Earth is a perfect sphere. tan(+)=gg2REtan , where is the angular velocity of Earth.
Must engineers take Earth’s rotation into account when constructing very tall buildings at any location other than the equator or very near the poles?
