At the distance of the earth from the sun, the pressureexerted by sunlight is about 10-5 Pa. How muchforce does this pressure exert on a 10 m2 array of solarcells on a satellite when the array is perpendicular to thedirection of the sunlight? If the satellite has a mass of 200kg, what acceleration does this force give it?
Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 300km above the earth's surface; at the high point, or apogee, it is 2500km above the earth's surface. What if the rockets were fired ..
