A ball has a mass of 0.273 kg just before it strikes the earth after being dropped from a building 52.3 m tall. It's de broglie wavelength is 0.75x10^-34m.
The de broglie equation is-
λ= h/mv
we know h and m, so we can now calculate velocity v. To calculate v of a ball, we need to know the physics formula for the velocity of a falling object after it has dropped from a building of a given height ---
v=√2gh
where g is the acceleration due to gravity and h is the height of the building.
v=√2*9.8*52.3
v=32m/s
Now, as-
λ= 6.626*10^-34 kg.m^2/s
0.273kg*32m/s
λ= 0.75*10^-34m
