As part of a daring rescue attempt, the Millennium Eagle coasts between a pair of twin asteroids, as shown in the figure below where d1 = 2.55 km and d2 = 1.28 km. The mass of the spaceship is 2.53 x10^7 kg and the mass of each asteroid is 3.70x10^11 kg. Find the speed of the Millennium Eagle at point A if its speed at point B is 0.990 m/s.

i keep getting 0.7932 m/s but its incorrect because it differs from the actual answer by 10%.
