Question

What is the magnitude of the velocity of a 25-kilogram object that has a momentum of 100 kilogram meters per second?

Answer 1

The velocity is `4 \ "m/s"`.

Explanation:

Momentum is defined by the equation

`p=mv`

where `m` is the mass of the object in kilograms, `v` is the velocity in `"m/s"`

We got:

`100 \ "kg m/s"=25 \ "kg"*v`

`v=(100color(red)cancelcolor(black)"kg""m/s")/(25color(red)cancelcolor(black)"kg"`

`=4 \ "m/s"`

So, the velocity of the object will be `4 \ "m/s"`.
