`A` golf ball has a mass of `40g` and a speed of `45m//s`. If the speed can be measured within accuracy of `2%`, calculate the uncertainty in the position.

Explanation

The uncertainty in the speed is 2%, i.e.,
`45 xx (2)/(100) = 0.9 ms^(-1)`
using the equation `Delta x = (h)/(4pi m Delta v)`
`= (6.626 xx 10^(-34)Js)/(4 xx 3.14 xx 40 xx 10^(-3)kg xx 0.9 ms^(-1)) = 1.46 xx 10^(-33)m`
