Question

Among the largest passenger ships currently in use, the Norway has been in service the longest. The Norway is more than 300 m long, has a mass of 6.9x10^7 kg, and can reach a top cruising speed of 9 m/s. Calculate the magnitude of the ships momentum

Answer 1

6.9x10^7

Step-by-step explanation:

Answer 2

The magnitude of the momentum of an object is given by:

`p=mv`
where m is the mass of the object, and v is its velocity.

In our problem, the mass of the ship is
`m=6.9 \cdot 10^7 kg` while its velocity is
`v=9 m/s`, so the momentum of the ship is

`p=mv=(6.9 \cdot 10^7 kg)(9 m/s)=6.21 \cdot 10^8 kg m/s`
