A satellite is initially in a circular orbit around the earth with radius ro. This initial orbit is shown in the upper left drawing. At the position marked by x in the drawing the satellite's rocket motor is fired briefly (assume instantaneously), giving the satellite an impulse in the direction of its motion (i.e. tangentially). This impulse changes the velocity of the satellite to Avo. The impulse is such that the farthest point from the earth that the satellite will reach is 2ro. (a) mass, M for the earth's mass, G for the gravitational constant, and vo for the velocity. Find the initial velocity of the circular orbit. Use m for the satellite (b) of the satellite? Explain your answer, perhaps by saying what is wrong with all the incorrect drawings. Which of the drawings below correctly shows the subsequent path (c) factor by which the velocity must be increased so that the farthest distance from the earth will be 2ro. Use conservation of energy and angular momentum to find A, the Note: the labels in the figure below do not refer to the parts of the problem. (a) (b) (c) (d) (e)

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.
