Velocity = 22.11 m/s

Explanation:

Using the equation;

λ = h / mv;

where

λ = wavelength (3.46 x 10^-33)

m = mass of the marble (8.66 g)

v = velocity (we gotta find out)

h = planck's constant (6.626 * 10^-34)

Making v the subject of the formula;

V = h / mλ

= (6.626 x 10^-34) / 0.00866 (3.46 x 10^-33)

= 22.1135

≈ 22.11 m/s
