## Homework Statement

Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2πJ · 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?

1(b) Assuming this uncertainty in speed to prevail for 5.40 s, determine the uncertainty in Fuzzy's position after this time.
