Homework Statement



An 2000kg car is traveling with a speed of (22 (+/-) 0.25) m/s.
With what maximum accuracy can its position be determined?

Homework Equations



(deltaX)(deltaP)>=h/2pi

The Attempt at a Solution



My attempt was solving for deltaX in the above equation. I used (1.06*10^-34 Js) for the h/2pi and then divided by the mass*velocity which would be (2000kg*22m/s). I don't know how to take into consideration the (+/-).25, or if that is even relevant to the problem.
 

Discussion

Sure it's relevant. You don't want to divide by P. You want to divide by deltaP, the uncertainty in the momentum.
