What speed does a 006 kg golf ball have if its de Brogliewav

What speed does a 0.06 kg golf ball have if its de Brogliewavelength is 4.25 x 10-34m?

Solution

We know that :
                 de Broglie wavelength       = h / P
                                                           = h / m v
                     velocity (v)   =    h / m
                                            = (6.62 x 10-34 ) / (0.06 * 4.25 x 10-34 )
                                            = 25.96 m /s
Hope this helps u!
