7th edition 1B.27 [ENDORSED]

This question gives the velocity of the bowling ball to be 5.00 +/- (plus or minus) 5.0 m/s. I plugged 5.0 m/s into the uncertainty formula and got the right answer. My question is why? The total uncertainty would be 10.0 m/s correct? This doesn't give me the correct answer though.

You're totally right in that the uncertainty of velocity should be 10m/s. The textbook and solution manual made a mistake. You can see the error addressed in the "Solution Manual Errors in the 6th Edition" link Dr. Lavelle has on his site (it is not listed on the 7th edition errors link, but you can see it is the same problem).

I was right all along then! Haha thank you so much

I have added this to the 7th edition list of errors.
