Chapter 39: Problem 82
Imagine another universe in which the value of Planck's constant is 0.0663 J \(\cdot\) s, but in which the physical laws and all other physical constants are the same as in our universe. In this universe, two physics students are playing catch. They are 12 m apart, and one throws a 0.25-kg ball directly toward the other with a speed of 6.0 m/s. (a) What is the uncertainty in the ball's horizontal momentum, in a direction perpendicular to that in which it is being thrown, if the student throwing the ball knows that it is located within a cube with volume 125 cm\(^3\) at the time she throws it? (b) By what horizontal distance could the ball miss the second student?
