Obviously, we can make rockets to go very fast, but what is a reasonable top speed? assume that a rocket is fired from rest at a space station in deep space, where gravity is negligible. assume that c = 3.00 108 m/s.

I’ve answered this problem before and there were 2 parts in this problem.

The solution would be like this for this specific problem:

A.    Vf = Vi + Vex*ln(Mi / Mf) 
0.002 * 3e8m/s = 0 + 2000m/s * ln(Mi / Mf) 
300 = ln(Mi / Mf) 
1.9e130 = Mi / Mf 

B.    4000m/s = 2000m/s * ln(Mi / Mf) 
2 = ln(Mi / Mf) 
7.389 = Mi / Mf 
Mf = Mi / 7.389 = 0.135*Mi 

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the components of a vector are the parts of the vectors that are to each other.
