Question

How much momentum does a `1/4 kg` object moving at `32 m/s` have?

Answer 1

See explanation.

Explanation:

Momentum is calculated as a vector with value equal to product of velocity (`v`) and mass (`m`) and direction equal to the direction of velocity vector.

`vec(p)=m*vec(v)`

Here the value is:

`p=1/4*32=8 [kg*m/s]`

Answer 2

`8 \ "kg m/s"`

Explanation:

Momentum of an object is given by the equation:

`p=mv`

• `m` is the mass of the object

• `v` is the velocity of the object

So, plugging in our given values into the equation, we get:

`p=1/4 \ "kg"*32 \ "m/s"`

`=8 \ "kg m/s"`
