wavelength = h/mv
h = Planck's constant
m = mass in kg
v is velocity in m/s
At what speed must a neutron travel to have a wavelength of 9.2 pm?

So the solution to the problem is v= wavelength x h/m?
nope
is it V=h/m x wavelength
yes.
I put into my calculator (6.626e-34)/(9.109e-31)(0.92e-11)= 6.69e-15 m/s but it is wrong, so what did I mess up?
