1. A baseball weighs 220 g. Top speed for a professional pitcher isabout 100 mph when he throws a fast ball. Find the de Brogliewavelength (in nm) associated with a baseball that is moving with avelocity of 70 mph.

2. Find theuncertainty in position (in nm) associated with an electron that ismoving with a velocity of 417 km/s. The uncertainty in the velocityis 5.00%. The electron rest mass is 9.11 x 10^-31 kg.(Use delta x * delta v >= h/4 pi m; Hint: > is ignored forthis type of problem)
