You can put this solution on YOUR website! The speed of a bullet,v m/s,form a gun is inversely proportion to the square root of its mass, m.When the mass is 64g,the speed is 850m/s.
What is the formula connecting m and v?
-----
v = k/sqrt(m)
---
Solve for "k":
850 = k/sqrt(64)
----
850 = k/8
k = 8*850 = 6800
---
Formula:
v = 6800/sqrt(m)
