    dа ta:

    mass = 45 g = 0.045 kg

    velocity = 72 m/s

    Formula:

    wavelength = Planck constant / (mass * velocity)

    Solution:

    Planck constant is 6.63 * 10^ - 34 J*s

    => wavelength = 6.63 * 10 ^ - 34 J*s / (0.045 kg * 72 m/s)

    wavelength = 2.05 * 10^ - 34 m

    Answer: 2.05 * 10 ^ - 34 m
