Question

2.34 At what true anomaly does the speed on a parabolic trajectory equal a times the speed at the
periapsis, where a < 1?

Expert Solution

Step 1

Initial velocity in x = v'_x

Initial velocity in y = v'_y

Final velocity in x diarection is v_x = v'_x

Final velocity in y direction v_y= v'_y -gt
