### Quiz 1 prep #5 question

For this problem it also asks "Can you blame the heisenberg uncertainty principle when your ball misses the the pins?"

I'm not sure how we are supposed to determine this. Is there supposed to be a specific number that your minimum indeterminacy in position needs to be to determine this?

I don't believe there's a specific number. However, if you did solve for the minimum indeterminacy of its position, you will see that the minimum indeterminacy in position is an extremely small number. So you can't blame the Heisenberg Uncertainty Principle if you miss the pins because the indeterminacy in position is so small.

On the topic of Indeterminacy: do you guys know what do write in the equation for "delta x" if the position is known withing plus or minus a certain number? (let's say plus or minus 0.55). Thanks.

You double what comes after the +/- to capture the whole range of uncertainty.

So then for the above problem, quiz 1 prep # 5, when solving for the indeterminacy in position, would delta V equal .2 because it would 0.1 doubled?

Yes that is correct. So delta P is 4.02 X 0.2.

Where does the 4.02 come from?

4.02 kg is the given mass of the bowling ball in the problem.
