(a) A 60 kg person, is in a room that is 6 meters long. Can this person be certain that they is not moving, even if to all appearances they are sitting perfectly still? If not, then estimate within what range their velocity is likely to be (you may assume that their average speed is zero).

(b) Find the size of the smallest one-dimensional box in which you can confine an electron, in order to be sure that the speed of the electron is always less than 5 m/s (assuming its average speed is zero).
