As discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?

- Thinking Mathematically: Explore the quantitative dependencies of the acceleration upon the speed and the radius of curvature. Then answer the following questions. Choose the right answer in the parenthesis. 1. As the radius of the circle is doubled, the acceleration is (one-fourth, one-half, two times, four times) the original value. 2. As the radius of the circle is tripled, the acceleration is (one-third, one-ninth, three times, nine times) the original value. 3. If your pig were made to fly at the same speed but in a circular path with a smaller radius, the tension in the string would be (less, more). 4. If your pig were made to fly at the same speed but in a circular path with a smaller radius, the centripetal force on the pig would be (more, less).arrow_forwardDrag the moon to various locations in order to determine the quantitative effect of distance upon the gravitational force. Examine the effect of doubling, tripling and quadrupling the distance of separation (as measured from planet'scenter). Consider the planet'ssurface to be a distance of one Earth-radius (1 Rplanet).
