hey guys, im having trouble with the heisenberg uncertainty principle equation! can any1 help me with this question?

Given that the mass of an electron is 9x10^-31kg, calculate the lowest uncertainty in position and velocity for the electron.

(i think this is meant to be a really easy Q but i still dont get it *sigh)

^{[math]\Delta[/math]}x^{[math]\Delta[/math]}p > hbar

 

but p=mv, and you know the mass

 

solve for ^{[math]\Delta[/math]}x^{[math]\Delta[/math]}v

but there r 2 variables to be solved...if u put in the mass, u will have 2 variables left and only that one equation...how can u find the value of each of the variables itself? wouldn't u need another equation for that?

I interpret the question as asking for the product.
