Calculate the de Broglie wavelength associated with a body of mass 1.5 kg moving with a velocity of 100m/s.

wavelength = h/mv

To calculate the de Broglie wavelength, we can use the de Broglie wavelength equation:

λ = h / p

Where:
- λ is the de Broglie wavelength
- h is the Planck's constant (6.626 x 10^-34 J·s)
- p is the momentum of the body.

To obtain the momentum, we can use the equation:

p = m * v

Where:
- p is the momentum
- m is the mass of the body
- v is the velocity of the body.

Let's calculate the momentum (p) first:

p = 1.5 kg * 100 m/s
p = 150 kg·m/s

Now, we can calculate the de Broglie wavelength (λ):

λ = h / p
λ = 6.626 x 10^-34 J·s / 150 kg·m/s

To simplify the equation, we can convert the units of h to kg·m²/s:

λ = 6.626 x 10^-34 kg·m²/s / 150 kg·m/s

Calculating this equation yields the de Broglie wavelength:

λ ≈ 4.417 x 10^-36 meters
