Question

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

Answer 1

mass x displacemet/time

Answer 2

Answer: To find momentum, we use the expression
`\frac{\text{Mass}* \text{Displacement}}{\text{Time}}`

Step-by-step explanation:

We are given:

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

Mathematically,

`p=m* v` ......(1)

And,

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

Mathematically,

`v=(d)/(t)` .....(2)

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

`p=(m* d)/(t)`

Or,

`\text{Momentum}=\frac{\text{Mass}* \text{Displacement}}{\text{Time}}`

Hence, to find momentum, we use the expression
`\frac{\text{Mass}* \text{Displacement}}{\text{Time}}`
