The average distance of the earth from the sun is about 1.5 × 10^8 km. assume that the earth’s orbit around the sun is circular and that the sun is at the origin of your coordinate system. (a) estimate the speed of the earth as it moves in its orbit around the sun. express your answer in miles per hour with the appropriate number of significant figures. (b) estimate the angle θ between the position vector of the earth now and what it will be in 4 months. (c) calculate the distance between these two positions.
