Imagine playing baseball in a universe (not ours!) where the Planck constant is 0.70 J·s. What would be the uncertainty in the position of a 0.55 kg baseball that is moving at 22 m/s along an axis if the uncertainty in the speed is 0.5 m/s?

Answer:

The uncertainty the  in position is  [tex]\delta s = 0.4051 m[/tex]

Explanation:

From the question we are  told

   The planck's constant is [tex]h = 0.70 \ J \cdot s[/tex]

  The mass of the baseball is  [tex]m = 0.55kg[/tex]

   The velocity of the baseball [tex]v_b = 22 m/s[/tex]

    The uncertainty in [tex]\delta v = 0.5 m/s[/tex]

   

Generally the uncertainty of  momentum is  

        [tex]\delta p = m \delta v[/tex]

 substituting values

        [tex]\delta p = 0.275 \ kg m/s[/tex]

The uncertainty position is mathematically represented as

             [tex]\delta s = \frac{h}{2 \p \delta p }[/tex]

 substituting values  

           [tex]\delta s = \frac{0.70}{2 * 3.142 * 0.275 }[/tex]

           [tex]\delta s = 0.4051 m[/tex]
