Assuming that the smallest measurable wavelength in an experiment is 0.330 fm (femtometers), what is the maximum mass of an object traveling at 157 m·s^–1 for which the de Broglie wavelength is observable?

mass = ? kg

wavelength = h/mv

Substitute wavelength (in meters) with v = m/s and solve for mass in kg.
