A golf ball has a mass 40g and a speed of `45 ms^(-1)`. If the speed can be measured with an accuracy of `2%`, calculate the uncertainty in position. 

Explanation

`Deltav=`The uncertainty in spced is `2%=45xx(2)/(100)=0.9ms^(-1)`
Using the equation, `Deltax=(h)/(piDeltav xxm)=(6.626xx10^(-34)kgm^(2)s^(-1))/(4xx3.1416xx0.9ms^(-1)xx40xx10^(-3)kg)=1.46xx10^(-33)m`
This is nearly `10^(18)` times smaller than the diameter of a typical atomic nucleus.
