Question

A 4.80×106 kg asteroid and a smaller 1.70×104 kg asteroid orbit around each other, keeping a constant distance 6.20×103 m. How far is the center of mass from the 4.80×106 kg asteroid?

____________m

Answer 1

Solution: To find the center of mass from the 4.80x10 kg asteroid is, m) m +m2 (4.80x10 kg +1.70x10 kg) (620x10'm) (4.80× 106kg +1.70×104kg) (480kg +1.70kg)×104 (6.20×103 m (480kg+1.70kg)x10 =6.2×103m Therefore the distance due to center ofmass from the 4.80x10*kg asteroid is 6.2 km
