Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2?J · s. Fuzzy has a mass of 1.95 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 5.40 s, determine the uncertainty in Fuzzy's position after this time.
