Predict/Calculate An Asteroid with its 0 wn Moon The asteroid 243 Ida has its own small moon, Dactyl. (See the photo on p. 394 . Another such system, asteroid 624 Hektor, has a mass of 7.9 ×10^18 kg, with its moon orbiting at a radius of 623.5 km and a period of 2.965 days. (a) Given that the orbital radius of Dactyl is 108 km, and its period is 1.54 days, is the mass of 243 Ida greater than, less than, or equal to the mass of 624 Hektor? (b) Calculate the mass of 243 Ida. | Numerade

The asteroid 243 Ida has a mass of about 4.0 ×10^16 kg and an average radius of about 16 km (it's not spherical, but you can assume it is). (a) Calculate the acceleration of gravity on 243 Ida. (b) What would an astronaut whose earth weight is 650 N weigh on 243 Ida? (c) If you dropped a rock from a height of 1.0 m on 243 Ida, how long would it take for the rock to reach the ground? (d) If you can jump 60 cm straight up on earth, how high could you jump on 243 Ida? (Assume the asteroid's gr

In 1993 the spacecraft Galileo sent an image (Fig. 13-48 ) of asteroid 243 Ida and a tiny orbiting moon (now known as Dactyl), the first confirmed example of an asteroid- moon system. In the image, the moon, which is 1.5 km wide, is 100 km from the center of the asteroid, which is 55 km long. Assume the moon's orbit is circular with a period of 27 h . (a) What is the mass of the asteroid? (b) The volume of the asteroid, measured from the Galileo images, is 14100 km^3 . What is the density (mass
