Textbook Problem 1B.27

Postby Megan Singer 3D » Tue Oct 27, 2020 3:49 pm

1B.27 A bowling ball of mass 8.00 kg is rolled down a bowling alley lane at 5.00±5.0 m⋅s−1. What is the minimum uncertainty in its position?

I tried solving this equation by plugging in delta x = h/4(pi)(8.00 kg)(10 m.s^-1). However, I keep on getting delta x = 6.6x10^-37 m instead of the textbook answer, 1.3 x 10^-36 m. Can someone explain where I went wrong?

Hi Megan!

Your answer is correct. The textbook makes the error of using 5 for delta v instead of 10. Dr. Lavelle addresses this in his Solution Manual Errors file on his website :-)
