Suppose you went for a drive along a long, straight road that runs east-west. Let's define east to be the positive x direction. From your home, you drive east at 30. mi/hr to your friends house for 20. minutes, then at 48 mi/hr east for 10. minutes to the grocery store. Finally, you drive west at 60. mi/hr without stopping to get home. How many minutes will it take to drive from the grocery store to your home (at 60. mi/hr)? Note: Your answer should have the correct number of significant figures
You hopefully used g=9.8 m/s2 (or thereabouts). That is the gravitational acceleration near the earth's surface. if you rise high above the earth, the gravitational acceleration decreases. Specifically, the gravitational acceleration is inversely proportional to the square of the distance from the earth's center. Equivalently, if you multiply the acceleration by the distance from the earth's center, you should get the same number for all heights. For this problem, take the radius of the earth as 3,902 miles, and calculate the gravitational acceleration of a satellite in low orbit, 182 miles above the surface.
