### Post Module Heisenberg Uncertainty Assessment

How do you calculate deltaV from this problem?
You are caught in a radar trap and hope to show that the speed measured by the radar gun is in error due to the Heisenberg uncertainty principle. If you assume that the uncertainty in your position was +/- 5 m when your speed was measured, and that the car has a mass of 2150 kg, what is your calculated uncertainty in the speed of your car?

Remember to use the heisenberg uncertainty principle inequality:$\Delta p*\Delta x\geq h/4\Pi$

$\Delta p*\Delta x\geq h/4\Pi$
$m*v\geq h/4\Pi (\Delta x)$
$v\geq h/4\Pi *m(\Delta x)$

$v\geq h/4*\Pi *(2150kg)*10 meters$

$v\geq 2.45 * 10^-39$ meters/second

Since the uncertainty in speed is so low(10^-39), this calculation will not help you if you are caught in a radar trap.
