`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 incertainity in the speed is `2%`, i.e., `45xx2/100=0.9 m s^(-1)`.
Using the equation, `Deltax=(h)/(4pim Deltav)=(6.626xx10^(-34))/(4xx3.14xx40xx10^(-3)(0.9 ms^(-1)))=1.46xx10^(-33) m`
This is nearly `~10^(18)` times smaller than the diameter of a typical atomic nucleus. As mentined earlier for large particles, the uncertainity principle sets no meaningful limit to the precision of measurements.
