According to heisenberg's uncertanity-
increment x equals lambda equals fraction numerator h over denominator m V end fraction increment x cross times increment P greater-than or slanted equal to fraction numerator h over denominator 4 pi end fraction increment P equals m increment V fraction numerator h over denominator m V end fraction cross times m increment V greater-than or slanted equal to fraction numerator h over denominator 4 pi end fraction fraction numerator increment V over denominator V end fraction greater-than or slanted equal to fraction numerator h over denominator 4 pi end fraction V less or equal than 4 pi increment V
You can see Velcoity is uncertain.
