The International Space Station Is Orbiting at an Altitude of About

Short Answer

The International Space Station is orbiting at an altitude of about 370 km above the earth's surface. The mass of the earth is $5.97 \times 10 ^ { 24 } \mathrm {~kg}$ the radius of the earth is $6.38 \times 10 ^ { 6 } \mathrm {~m}$ and $G = 6.67 \times 10 ^ { - 11 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { kg } ^ { 2 }$ Assume a circular orbit.
(a) What is the period of the International Space Station's orbit?
(b) What is the speed of the International Space Station in its orbit?
