1. The problem statement, all variables and given/known data
Heisenberg's uncertainty principle can be expressed mathematically as Delta X * Delta P = h/4 (pie[3.1414]), where Delta X and Delta P denote the uncertainty in position and momentum respectively an h is Planck's constant. What would be the uncertainty in the position of a fly (mass = 1.054 g) that was traveling at a velocity of 3.475 m/s if the velocity has an uncertainty of 1.44%?
2. Relevant equations
Plug and chug: Heisenberg's uncertainty principle formula.
Delta P = m * Delta V
3. The attempt at a solution
Delta X = (h/4pie) * (1/ [Delta V * mass])
[Delta V * mass] = 1.054 g x (1 kg / 1000g) x (1.44 / 100) x 3.475 = 5.274216 x 10-5
Delta X = {(6.626 x 10-34) / 4 pie} / 5.274216 x 10-5 = 2.74472744 x 10-38
