Which of these calculations could you use to find momentum if momentum is equal to mass times velocity and velocity is equal to displacement divided by time?


mass×displacement÷time


mass×time


length×time


mass×distance×time

Respuesta :

Answer:

mass x displacemet/time

Answer: To find momentum, we use the expression [tex]\frac{\text{Mass}\times \text{Displacement}}{\text{Time}}[/tex]

Explanation:

We are given:

Momentum is equal to mass multiplied by velocity of an object.

Mathematically,

[tex]p=m\times v[/tex]      ......(1)

And,

Velocity is equal to the rate of change of displacement with respect to time.

Mathematically,

[tex]v=\frac{d}{t}[/tex]      .....(2)

Putting the value of velocity from equation 2 to equation 1, we get:

[tex]p=\frac{m\times d}{t}[/tex]

Or,

[tex]\text{Momentum}=\frac{\text{Mass}\times \text{Displacement}}{\text{Time}}[/tex]

Hence, to find momentum, we use the expression [tex]\frac{\text{Mass}\times \text{Displacement}}{\text{Time}}[/tex]
