Asteroid Ida was photographed by the Galileo spacecraft in 1993, and the photograph revealed that the asteroid has a moon, which has been named Dactyl

From the dimensions of Ida and its general features, one can estimate the mass of Ida to be 4.5 × 1016 kg, and the distance between Dactyl and Ida is approximately 90 km. Assuming a circular orbit, what would be the orbital speed of Dactyl? G = 6.67 x 10-11 N•m2/kg2. A) 5.8 m/s B) 11 m/s C) 2.3 m/s D) 2.9 m/s E) 30 m/s
