How do you treat a square root of a negative square?
I am converting the units √(kg*J)/N into SI-Units. This leads me to √(s^-2)/(s^-2) . How would this solve out?

simply √(s^-2) = s^-1

By the way √(kg*J)/N  is already a SI unit ;-)
you just need to simplify this expression.

Great!, thank you for your help.

Simplifying the equation was basically the entire exercise, a pretty simple one at that, but I felt stumped by the negative exponents for a minute. That clears it up for me.

Again, cheers!
