Question about HW1.45 and how to determine the incertainty of velocity [ENDORSED]

1.45 A bowling ball of mass 8.00 kg is rolled down a bowling alley lane at 5.00+/-5.0m/s. What's the minimum uncertainty in its positon? The student solution manual take 5m/s as the delta v. I feel confused because based on what i learned from the video, the delta v in this question should be double...

Re: Quantum World - Light

Etotal=W=p*t=40w*2.0s=80J
Ephoton=hc/λ
number of photon=Etotal/Ephoton
n(amount in mole)=number of photon/Avogado's constant
hope this can help you!
