A car with mass is heading toward a wall at a speed $25\frac{m}{s}$ . What is the approximate de Broglie wavelength of the car?

$h = 6.626\times 10^{-34}~\text{J}\cdot\text{s}$

$1.33\times10^{-38}~\text{m}$

$2\times10^{-34}~\text{m}$

$80~\text{m}$

$0.0125~\text{m}$

$532\times10^{-9}~\text{m}$

The de Broglie wavelength is given by $\lambda = \frac{h}{m v}$ .
