Hello. for each marked location I need help plotting/drawing the direction of the velocity vector and the acceleration vector?This is an ellipse with a 5 au and e=0.5. I know the first one 0=61 looks like a reverse right angle.

14 0-610 63 degrees, Increasing 1 4 0= 63 80degrees, increasing 80degrees increasing 1 40= 80 0 = 80 100, decreasing 1 40= 100 1 40 = 100 100, Decreasing 118degrees, Decreasing 1 4 0= 115 1 40-118 115 Degrees, decrease
