(a) Assume an electron in the ground state of the hydrogen atom moves at an average speed of 5.00 times 10^6 m/s. If the speed is known to an uncertainty of 1 percent, what is the minimum uncertainty in its position? The radius of the hydrogen atom in the ground state is 5.29 times 10^-11 m. The mass of an electron is 9.1094 times 10^-31 kg. (b) A 0.13-kg baseball thrown at 100 mph has a momentum of 5.9 kg middot m/s. If the uncertainty in measuring the mass is 1.0 times 10^-7 of the mass, calculate the uncertainty in the baseball's position.
