As the question depicts the mass of golf ball is 45.9grams and is leaving with the speed of 62.0m/sec, the wavelength is $2.328\times10^{-34}$ m

What is Wavelength?

Wavelength is the distance between the successive crests of the wave, especially in the sound waves.

The wavelength is determined by the de Broglie formula which is given below,

$\lambda=\frac{h}{mv}$

here,

h= Plank's constant = $6.626\times 10^{-34} Jsec$

m= Mass of the object = 45.9 grams = $45.9\times10^{-3}$

v= Velocity of the object = 62.0 m/sec

so,

$\lambda=\frac{6.626\times10^{-34} }{(45.9\times10^{-3})(62.0) }$

$\lambda=2.328\times10^{-34}$ m

So, the corresponding wavelength is $2.328\times10^{-34}$ m

The wavelength of the golf ball is 2.328×10⁻³⁴m.

All moving particles with mass have a matter wave associated with it. These matter waves are called deBroglie waves.

The deBroglie wavelength λ of a particle is given by,

$\lambda=\frac{h}{mv}$

Here, h is the Planck's constant, m is the mass of the ball and v is its velocity.

Calculate the deBroglie wavelength of the moving golf ball by substituting 6.626×10⁻³⁴J s for h, 45.9×10⁻³kg for m and 62.0 m/s for v.

$\lambda=\frac{h}{mv}\\ =\frac{6.626*10^-^3^4Js}{(45.9*10^-^3kg)(62.0m/s)} \\ =2.328*10^-^3^4m$

The wavelength of the golf ball is 2.328×10⁻³⁴m.

Answer from: Quest

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
