Homework Statement
18. A ball of mass 50 g moves with a speed of 30 m/s. If its
speed is measured to an accuracy of 0.1%, what is the
minimum uncertainty in its position?
19. A proton has a kinetic energy of 1.0 MeV. If its momentum
is measured with an uncertainty of 5.0%, what is
the minimum uncertainty in its position?
Homework Equations
[tex]\Delta[/tex]p[tex]\Delta[/tex]x [tex]\geq[/tex][tex]\frac{h}{4\pi}[/tex]
The Attempt at a Solution
I know how to solve #19, because I know that [tex]\Delta[/tex]p / p = uncertainty. But what about accuracy? Do they mean the same thing? How does accuracy relate to [tex]\Delta[/tex]p or [tex]\Delta[/tex]x or the uncertainty of one of those?
Thanks!
