Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2πJ · s. Fuzzy has a mass of 2.00 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?
(b) Assuming this uncertainty in speed to prevail for 5.00 s, determine the uncertainty in Fuzzy's position after this time.
