<PRE><B>Question 989953</B>
 The total mechanical energy of an object with mass 
m at height 
h in a closed system can be written as 
ME = 1/2mv^2 + mgh. Solve for v, the velocity of the object, in terms of the given quantities.
------
2ME = mv^2 + 2mgh
------
mv^2 = 2(ME-mgh)
-----
v = sqrt[2(ME-mgh)/m]
