the uncertainty in its velocity is 5 % ?

Hey there! Here is the solution.

Notice here we need to convert the mass into kg. Also, knowing that the uncertainty in velocity is 5%, that means the delta v we use in the equation will be +/- 5%. To find the uncertainty in velocity you first multiply the average velocity by 0.05, this gives us 68. So you have to calculate delta x twice, one by adding 68 to the velocity, second by subtracting 68 from the velocity. We are going to have a range for uncertainty in position, between 1.1115x10^-11 and 1.2285x10^-11. Hope this makes sense, let us know if you have any more questions about this.

- I tried this answer and it says "Your answer either contains an incorrect numerical multiplier or is missing one." Makenzie commented 12 months ago
- Hey, so if they are asking for one sig fig you would then put in for your answer just 1.x10^-11 m. Let us know if that doesn't work either, we'll try to figure this out. Dasha commented 12 months ago
