Question

Which has more momentum, an object with a mass of `5kg` moving at `3m/s` or an object with a mass of `9kg` moving at `2m/s`?

Answer 1

The momentum of the second object is larger.

Explanation:

The formula for momentum is

`p = m*v`

Therefore you simply multiply mass times velocity for each object.

`5 " kg moving at " 3 m/s`:
`p_1 = 5 " kg " * 3 m/s = 15 ("kg*m)/s`

`9 " kg moving at " 2 m/s`:
`p_2 = 9 " kg " * 2 m/s = 18 ("kg*m)/s`

I hope this helps,
