Bottom image, Figure 3: A personal residence (Phoenix, Arizona). A spacecraft and a staellite are at diametrically opposite position in the same circular orbit of altitude 500 km above the earth. As it passes through point A, the spacecraft fires its engine for a short interval of time to increase its speed and enter an elliptical orbit. Knowing that the spacecraft returns to A at the same time the satellite reaches A after completing one and a half orbits, determine (a) the increase in speed required, (b) the periodic time for the elliptic orbit Can someone help me with this question pls and thank you Please help with math ASAP, will give brainliest!!

A water resources engineer is trying to run a cost-benefit analysis for a project. They need to first decide on the planning period (the benefits should be calculated over N years, and N should be determined). If N is too large, then the future benefits in those years (e.g. 70 years from now) will have a very low present value. Therefore, the engineer would like to cut off the planning period after a point when the present equivalent of benefits becomes less than 6.25% of that future benefit. If the interest rate is 8%, use the rule of 72 to determine the duration of the planning period (N).
