Textbook Problem

If a giant molecular cloud is 50 pc in diameter and a shock wave can sweep through it in 2 million years, how fast is the shock wave going in kilometers per second?

To determine

Velocity of the shock wave in kilometers per seconds.

Explanation

Given:

The diameter of the molecular cloud d= 50 pc

  d=50×3.086×1013 kmd=154.3×1013 km

Shock wave traveled time t= 2 million years

  t=2×106×365×24×60×60t=63
