How Do You Rearrange the Equation v = sqrt(2kt/m) to Solve for M?

Just need some help rearranging this equation to make M the subject, thanks

v = sqrt 2kt / m

 

[rock.freak667]

Start by squaring both sides.

 

[jim the duke]

sqrt v = sqrt 2kt / m

 

[jim the duke]

m = 2kt / v^2

Just need some help rearranging this equation to make M the subject,
v = sqrt 2kt / m

Start by squaring both sides.

sqrt v = sqrt 2kt / m

I see two mistakes in what you did:
1. rock.freak667 said to square both sides (not take the square root of both sides).
2. He said to do it to both sides, not just the left side.

v = sqrt 2kt / m

If the problem is v= sqrt(2kt/m) then, yes, start by squaring both sides to get rid of the square root.

If the problem is v= sqrt(2kt)/m, which is the way I first interpreted it, start by multiplying both sides by m.

Please use parentheses to make your meaning clear!
