With what maximum accuracy can its position be determined?

SUMMARY

The discussion focuses on determining the maximum accuracy of position for a 2000 kg car traveling at a speed of 22 m/s with an uncertainty of ±0.25 m/s. The relevant equation used is the Heisenberg uncertainty principle, expressed as (ΔX)(ΔP) ≥ h/2π. The correct approach involves calculating ΔP, the uncertainty in momentum, rather than using the total momentum. This distinction is crucial for accurately solving the problem.

PREREQUISITES
  • Understanding of the Heisenberg uncertainty principle
  • Basic knowledge of momentum and its calculation
  • Familiarity with quantum mechanics terminology
  • Ability to perform calculations involving physical constants
NEXT STEPS
  • Calculate ΔP using the given uncertainty in velocity (±0.25 m/s)
  • Explore the implications of the Heisenberg uncertainty principle in classical mechanics
  • Study examples of uncertainty calculations in quantum physics
  • Review the significance of Planck's constant in physical equations
USEFUL FOR

Students studying physics, particularly those focusing on quantum mechanics and uncertainty principles, as well as educators looking for practical examples of applying theoretical concepts.

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.

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