Abaseball weighs 220 g. top speed for a professional pitcher is about 100 mph when he throws a fast ball. find the de broglie wavelength (in nm) associated with a baseball that is moving with a velocity of 69 mph.

The de Broglie wavelength associated with a baseball is.

Explanation:

De-Broglie wavelength is calculated by using the formula:

     .....(1)

where,

= wavelength of particle

h = Planck's constant =

m = mass of particle

v = velocity of particle

We have :

m = 220 g =0.220 kg

velocity of the baseball , v= 69 mile/h

1 mile = 1609.34 m , 1 hour = 3600 s

v =

()

The de Broglie wavelength associated with a baseball is.
