I got:

#### Explanation:

We know that the deBroglie wavelength is:

#lambda=h/p#

where:

#h=6.63xx10^-34# #"J"cdot"s"# is Planck's constant;#p=mv# is the linear momentum.

We get:

#lambda=(6.63xx10^-34)/(0.01*10)=6.63xx10^-33# #"m"# ,

too small to be detected by any device.

This is indicative of a large, non-quantum system.
