45. (Ill) A Ferrari with a mass of 1400 kg approaches a freeway underpass that is 10 m across. At what speed must the car be moving, in order for it to have a wavelength such that it might somehow diffract" after passing through this single slit"? How do these conditions compare to normal freeway spe
