Problem 1B.27

Postby Katie Bart 1I » Tue Oct 22, 2019 9:35 pm

In this problem why do we only use 5m/s as the velocity and disregard the uncertainty of + or - 5?

On a previous discussion board, Professor Lavelle commented that the solutions guide has an error with this question.

Link to his comment: viewtopic.php?t=5558

Solution manual errors correction:
-Solution manual states Δv = 5.0 m.s-1
-Velocity was given as 5.00 ± 5.0 m.s-1
-Therefore Δv = 10.0 m.s-1
-With the correction, the final answer is: Δx = 6.7 x 10-37 m
