someone told me that if u throw a baseball down the field, it will exhibit a wave-like properties( or basically every moving objects exhibit a wave-like properties) I'm just wondering if it's true or not

Well, [math]p=\frac{h}{\lambda}[/math]. Rearranging, we get [math]\lambda=\frac{h}{p}[/math]. h=6.626068 × 10^-34 m²kg/s, which means the number is most likely ridiculously small.

 

The classical approximation for momentum is p=mv, so we need to find the mass and velocity. The average baseball is about 150g, or 0.15kg(via google). The average pitch is about 30m/s(again via google). The actual values don't really matter as much as the order of magnitude, so I'm not being very picky about the numbers.

 

Plugging in the numbers gives us a wavelength of about 1.5x10^-34m. So, yeah, it doesn't really behave much like a wave.
