? = h/mv is the deBroglie equation.
m is mass in kg; v is speed in m/s; h is Planck's constant = 6.626 x 10^-34 J*s
speed = 1313 mi/h(1609 m/1 mi)(1 h/3600 s) = 586.84 m/s
m = 7.41 g(1 kg)/(1000 g) = 0.00741 kg
? = (6.626 x 10^-34 J*s)/(0.00741 kg)(586.84 m/s)
1 J = 1 kg*m^2/s^2
? = 1.52 x 10^-34 m
