Answer:
The speed is 33.5 m/s.
Explanation:
Given that,
Mass = 0.064 kg
Wavelength [tex]\lambda= 3.09\times10^{-34}\ m[/tex]
We need to calculate the speed
Using formula of he de Broglie wavelength
[tex]\lambda=\dfrac{h}{mv}[/tex]
[tex]v=\dfrac{h}{m\lambda}[/tex]
Where, h = Planck constant
m = mass
[tex]\lambda[/tex] = wavelength
Put the value into the formula
[tex]v = \dfrac{6.63\times10^{-34}}{0.064\times 3.09\times10^{-34}}[/tex]
[tex]v=33.5\ m/s[/tex]
Hence, The speed is 33.5 m/s.
