Question
Mitch drops a $2.0$ -g coin into a $3.0$ -m-deep wishing well. What is the de Broglie wavelength of the coin just before it hits the bottom of the well?
Step 1
We can use the following equation for free fall: v^2 = u^2 + 2as where v is the final velocity, u is the initial velocity (0 in this case, since the coin is dropped), a is the acceleration due to gravity (9.81 m/s^2), and s is the distance fallen (3.0 m). v^2 = Show more…
