On one of the preparation quizzes there is a question that asks "Calculate the wavelength of a motorcycle of mass 275 kg traveling at a speed of 125 km/hr. I used the DeBroglie Equation and my final answer was 6.94x10^(-41) m. However the answer says that it's 6.94x10^(-38) m. I am not sure if I messed up on one of the conversions but I divided 6.626x10^(-34) J.s/(275000g)*(34.722 m/s) and got the answer I stated.
