Assuming that the smallest measurable wavelength in an experiment is 0.410 fm (femtometers), what is the maximum mass of an object traveling at 815 m*s^-1 for which the de Broglie wavelength is observable?

w = wavelength

w = h/mv

Convert w to meters, solve for m in kg.

I think you would be of more help if you actually answered the question instead of just giving the equation in all your posts.
