Answer 2

`0.23\:\mathrm{m/s}`

Explanation:

The momentum of an object is given by
`p=mv`, where
`m` is the mass of the object and
`v` is the velocity of the object.

What we're given:

• object's mass
  `m`
• object's momentum
  `p`

Substituting given values, we can solve for
`v`:

`2.1=9v,\\v=(2.1)/(9)\approx \boxed{0.23\:\mathrm{m/s}}`
