Assuming that the smallest measurable wavelength in an experiment is 0.350 fm, what is the maximum mass of an object traveling at 773 In - s'1 for

Could you provide a detailed calculation of the actual answer please. Thank you!

Assuming that the smallest measurable wavelength in an experiment is 0.350 fm, what is the maximum mass of an objecttraveling at 773 In - s‘1 for which the de Broglie wavelength is observable? m: 1.46 x10-15 9 kg
