Chapter 6, Problem 51E

Using Heisenberg's uncertainty principle, calculate the uncertainty in the position of

1. a 1.50-mg mosquito moving at a speed of 1.40 m/s if the speed is known to within ±0.01 m/s;
2. a proton moving at a speed of (5.00 ± 0.01) x 10⁴ m/s. (The mass of a proton is given in the table of fundamental constants in the inside cover of the text.)
