Calculate the force of gravity on a spacecraft 19200 km (3 earth radii) above the Earth's surface if its mass is 1600 kg.
Hint: At three earth radii from the surface of the Earth, the gravity force (weight) of the spacecraft will be reduced to
(1/4)^2 = 1/16 of the weight when the spacecraft is at the Earth's surface, since it is 4 times farther from the Earth's center.
(1/16) x M g = ?
g is the value at the Earth's surface, 9.8 m/s^2. M = 1600 kg.
