Question

What is the momentum of a `400"kg"` object moving with velocity `8"m"//"s"`?

Answer 1

`p=3200 (kgm)/s`

Explanation:

Momentum, `vecp`, is given by the product of an object's mass, `m`, and velocity, `vecv`.

`vecp=mvecv`

Given a mass of `400kg` and a velocity of `8m/s`,

`p=(400kg)(8m/s)`

`=>p=3200(kgm)/s`

Note that momentum is a vector quantity, but we have no specified a direction. Our calculated value, therefore, is a magnitude.
