Suppose a duck lives in a universe in which h = 2π J · s. The duck has a mass of 2.35 kg and is initially known to be within a pond 1.40 m wide.(a) What is the minimum uncertainty in the component of the duck's velocity parallel to the pond's width? (b) Assuming this uncertainty in speed prevails for 4.85 s, determine the uncertainty in the duck's position after this time interval.
