Homework Statement
A small flat circular disc of diameter 2mm and mass 5mg is lowered vertically to rest at the centre of a flat tray of width 10mm in the x direction and 50mm in the y direction. What is the minimum uncertainty in measuring the velocity of the particle in the x direction? Considering possible motion only in the x direction, determine whether it is likely that the disc would touch the side of the tray in a given time:
(a) overnight
(b) in the lifetime of the Universe (approx. 15 billion years)
