Problem: Andrea, whose mass is 50 kg, thinks she’s sitting at rest in her 5.0-m-long dorm room as she does her physics homework. Can Andrea be sure she’s at rest? If not, within what range is her velocity likely to be?

FREE Expert Solution

This problem is based on the Heisenberg uncertainty principle.

The principle places limitations in the accuracy when determining position and velocity simultaneously. 

Mathematically:

x·pxh4π Δx is the uncertainty in the position, Δpx is the uncertainty in the momentum, and h is planks constant.
