Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A satellite moves in a circular orbit around the Earth at a speed of 5 . 3 km / s. Determine the satellites altitude above the surface of the Earth. Assume the Earth is a homogeneous sphere of radius 6370 km and mass 5 . 98 10 24 kg. The value of the universal gravitational constant is 6 . 67259 10- 11 N m 2 / kg 2 . Answer in units of km. 002 10.0 points If our Sun were three times as massive as it is, how many times faster or slower should the Earth move in order to remain in the same orbit? 003 (part 1 of 2) 10.0 points Three masses are arranged in the ( x, y ) plane as shown. y [m]- 5- 3- 1 1 3 5 x [m]- 5- 3- 1 1 3 5 1 kg 2 kg 2 kg What is the magnitude of the result- ing force on the 1 kg mass at the ori- gin? The universal gravitational constant is 6 . 6726...
