Quiz Preparation #5 [ENDORSED]

[Jose_Arambulo_2I]

Hi, I'm just a tad confused with the 5th problem on the quiz 1 preparation (pg. 28). In the problem, it states that the bowling ball's speed is "2.35+/-0.1ms^-1." What then would the delta v value be if I'm trying to solve for delta p?

Delta v would be 2 times .1 which is .2, since .1 is the uncertainty in the velocity and the value of v can range from 2.25 to 2.45. You can also think of delta v as 2.45-2.25, which is .2. Hope this helps!
