Johnny Jumper's favorite trick is to step out of his high-rise window and fall 56.0 m into a pool. A news reporter takes a picture of 70.0 kg Johnny just before he makes a splash, using an exposure time of 7.00 ms. Find the following.

(a) Johnny's de Broglie wavelength at this moment

2. Relevant equations

wavelength = h / (mv) v = x/t

3. The attempt at a solution

so I know figured out v which is just 56 m / .007 s = 8000 m/s

I know m = 70 kg

I plug it in to the equation wavelength = (6.63e-34) / ((8000)(70)))

I got 1.18e-39 m. It saids I am wrong, plz help
