We’re being asked to calculate the speed of a 455 kg car and a de Broglie wavelength of 5.43 × 10–47 nm.
Recall that the de Broglie wavelength (λ) can be calculated using:
h = Planck's constant (6.626 × 10–34 kg • m2/s)
m = mass (in kg)
v = velocity (in m/s)
The de Broglie wavelength of a 455 kg car is found to be 5.43 × 10 –47 nm. Calculate the speed (m/s) of the car.
a) 26.8 m/s
b) 37.3 m/s
c) 2.68 × 1019 m/s
d) 3.73 × 107 m/s
e) 3.00 × 108 m/s
