Suppose Fuzzy, a quantum mechanical duck, lives in a world in which h = 2π J.s. Fuzzy has a mass

of 2.0 kg and is initially known to be within a region 1.0 m wide.

a) What is the minimum uncertainty in his speed?

b) Assuming this uncertainty in speed to prevail for 5.0 s, determine the uncertainty in position after

this time.
