1.	A golf ball has a mass 40g and a speed of 45 ms^(-1). If the speed can be measured with inaccuracy of 2%, calculate the uncertainty in position.
Answer» SOLUTION :The UNCERTAINTY in speed `= 45 XX(2)/(100) = 0.9 ms^(-1)` `"Using the EQUATION, "Deltax=(h)/(4piDeltavxxm)` `Deltax=(6.626xx10^(-34)kgm^(2)s^(-1))/(4xx3.1416xx0.9ms^(-1)xx416xx0.9ms^(-1)xx40xx10^(-3)KG)` `Deltax=1.46xx10^(-33)m` This is nearly 1018 times smaller than the diameter of a typical atomic nucleus.
