e. Devise a new graph of vavg against a different quantity derived from I" that will be a straight line (see next page). Measure its slope (including its units). Hint: use the equation for orbital velocity to guide your thinking. Enter the values for this graph in the last column of Table 1. f. Using digital resources such as the internet, research the average orbital speed for the eight planets. Compare the values with those you obtained from the simulation. Part 2: Transfer orbits In order to send a satellite from one planet to another, it is Tram m to Mars necessary to change the satellite's velocity by using a trajectory called a transfer orbit. Earth at 1. Select Earth. Determine the initial velocity necessary to launch propel a satellite initially from Earth's orbit to just reach x 'I'Ul'vnm'n nFL':I*
