    Consider a baseball of mass m=0.5 kg moving with a velocity v0= 50m/sec a good fast ball. the uncertainty in velocity is very low or it would be out of the classical realm. Suppose Delta V0/V0 -= 10^-20 . Use the uncertainty principle to determine the minimum uncertainty in the basaeball's position DeltaX at any given time. Now suppose that m=9.1X10^-31kg, the mass of the electron. What is the minimum DeltaX , assuming all other parameters remain unchanged? Note that...
