Question

A rocket with a mass of 1,000 kilograms is moving at a speed of 20 meters per second. What is the magnitude of the momentum?

Answer 1

`20,000 \ "kg m/s"`

Explanation:

Momentum is given by the equation,

`p=mv`

• `m` is the mass of the object in kilograms

• `v` is the velocity of the object in meters per second

And so, we get,

`p=1000 \ "kg"*20 \ "m/s"`

`=20,000 \ "kg m/s"`
