Question
Imagine another universe in which Planck's constant is 0.06626 Js, but in which the physical laws and all the other physical constants are the same as in our universe. In this universe, two people are playing catch with a 250 gram baseball. They are 12 m apart and one throws the ball towards the other with a speed of 6 m/s. Neglecting gravitational effects, determine the following:
a) The uncertainty in the ball's horizontal momentum delta px, in a direction perpendicular to that in which it is being
thrown, if the person throwing the ball keeps it confined within a cubical space of 125 cm^3 when it is thrown.
b) The horizontal distance by delta x by which the thrown ball could miss the other person.
Explanation / Answer
delta p = 0.06626/0.05 = 1.3252
B)1.5*12*delta x = 0.06626
delta x = 0.06626/1,5*12 =0.53m
