Question

calculate the uncertainty in the velocity wagon of mass 3000 kg. whose position to know to an accurecy of ±10 p.m

Answer 1

thank you!!!!! finally i saw a question with a great level.

Answer 2

This is based on Heisenbergs uncertainty principle.

The Heisenberg uncertainty principle states that it is impossible to know simultaneously the exact position and momentum of a particle. The more exactly the position is determined, the less known the momentum, and vice versa.

∆x∆v>= h/4πm

Calculating we get

∆v= 1.75*10^28 m/s2
