Question

Two meteoroids are 2.4×105 from Earth's center and moving at 2.1 . One is headed straight for Earth, while the other is on a path that will come within 8500 of Earth's center.Find the speed of the second meteoroid at its closest approach to Earth.

Answer 1

G=6,67259·10^−11
M=2,4 × 105
R=8500

v=sqrt(6,67259·10^{−11 ×}2,4 × 105/8500)=sqrt(0.2* 10^{−11)
v=1.41E-6}
