Answer 1

Complete Question

Calculate the wavelength, in meters, associated with a 56g golf ball moving at 20. m/s (about 45 mph).

Answer:

The value is $\lambda = 5.92 *10^{-34} \ m$

Explanation:

From the question we are told that

   The speed of the golf ball is  $v = 20 \ m/s$

    The mass is  $m = 56 \ g = 0.056 \ kg$

Generally from Broglie's equation we have that

       $\lambda = \frac{h}{mv }$

Here  h is the Planck constant with value  

      $h = 6.626 *10^{-34} \ kg\cdot m^2\cdot s^{-1}$

Here $\lambda$ is the wavelength associated with the golf ball

  So

           $\lambda = \frac{6.626 *10^{-34}}{ 0.056 * 20}$

=>        $\lambda = 5.92 *10^{-34} \ m$
