Problem

A baseball of mass

1.5\,\text{kg}

is thrown at

40\,\text{m\,s}^{-1}

. Using Planck’s constant

h=6.6\times10^{-34}\,\text{J\,s}

, which value is closest to the baseball’s de Broglie wavelength? a)

1.1\times10^{-25}\,\text{m}

1.8\times10^{-36}\,\text{m}

1.1\times10^{-35}\,\text{m}

2.8\times10^{-37}\,\text{m}
