Assume Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2πJ·s. Fuzzy has amass of 1.75 kg and is initially known to be within a pond 1.00 m wide.
a) What is the minimum uncertainty in his speed?
b) Assuming this uncertainty in speed to prevail for 5.10 s, decide the uncertainty in Fuzzy's position after this time.
