5. Calculate: The eccentricity of an ellipse is a number that describes the flatness of the ellipse. Eccentricity is equal to the distance between foci divided by the total width of the ellipse. There are no units for eccentricity Click Reset. Move the planet to r = -5.00i AU (does not have to be exact) and drag the velocity vector to set the velocity close to -8.03 km/s. Click Play, and then click Pause after one full revolution.
A. What is the distance between the foci?
B. What is the approximate width of the ellipse?
C. What is the eccentricity of the ellipse?
D. Click Reset, and change the initial velocity to -4.0j km/s.
Click Play. What is the eccentricity of this ellipse?
