I have been given the equation  y = sqrt 3kx/m Where k is a constant with units joules per kelvin m is a constant with units kg x has units kelvin How do I work out the SI units for y?

Treat the units as something you can substitute in for k, m and x. Rearrange and see what you come up with.

$\sqrt{\dfrac{\frac{J}{T} \cdot T}{kg}}$ $\sqrt{\dfrac{\frac{N \cdot m}{\cancel{T}} \cdot \cancel{T}}{kg}}$ $\sqrt{\dfrac{N \cdot m}{kg}}$ $\sqrt{\dfrac{\frac{kg \cdot m}{s^2} \cdot m}{kg}}$ $\sqrt{\dfrac{\frac{\cancel{kg} \cdot m^2}{s^2}}{\cancel{kg}}}$ $\sqrt{\dfrac{m^2}{s^2}}$ $\dfrac{m}{s}$
