Academics

Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2?J · s. Fuzzy has a mass of 1.80 kg and is initially known to be within a pond 1.00 m wide.

(a) What is the minimum uncertainty in the duck's speed?

m/s

(b) Assuming this uncertainty in speed to prevail for 4.70 s, determine the uncertainty in Fuzzy's position after this time.
