Imagine another universe in which the value of planck’s constant is 0.0663 Js, 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 towards the other with a speed of 6.0 m/s
By what horizontal distance could the ball miss the second student ?
- 3 m
- 30 m
- 17 m
- 1.7 m
Answer
(D) 1.7 m
