Question

Use Heisenberg's Uncertainty Principle to calculate the uncertainty in the position of a 546 mg ball moving at a speed of 5.3 m/s if the speed is known to be correct within
±0.05
m/s.

Answer 1

My Textbook defines the formula as
\[\Delta x \times \Delta (mv) \ge \frac{ h }{ 4\pi }\]

Answer 2

solve for \(\Delta x\)

Answer 3

Alright, but what should I plug in for each variable?

Answer 4

every value is given except for \(\Delta x\). Mass is given, and the uncertainty is given, h is a constant, and \(4\pi\) is a constant
