Velocity is calculated by distance and time

v = d/t
v = 8m/4s
v = 2 m/s

It's velocity is 2 meters per second

Speed  =  (distance covered) / (time to cover the distance)

           =        (8 m)            /          (4 s)

           =         ( 8 / 4 )  m/s

           =             2 m/s   .  

That 's the toy car's speed.  We can't tell its velocity,
since we have no information about its direction.

Hi there!

We can use Newton's Second Law:

\Sigma F = ma

∑F = net force (N)

m = mass (kg)

a = acceleration (m/s²)

We are given the mass and acceleration, so:

∑F = 20 · 2 = <u>40 N</u>

Explain the difference between what Isaac Newton and Louis de Broglie would have to say about the momentum of a particle that is
pishuonlain [190]

Answer:

Explained

Explanation:

Newton would resort to the classical mechanics and say that the momentum of the particle that is moving with a constant velocity will be given by: momentum = mass x velocity

this approach will highlight the particle nature and will not be relativistic.

De-Broglie will say that the momentum of the particle is related to its associated matter wave and the relation between them is given by:

p = \frac{h}{\lambda}

where \lambda = wavelength of the matter wave associated to the particle, h = planck's constant

andp = \gamma\times mv

thus, this highlights the wave nature of the particle and is also relativistic.
