A train car of mass 16,500 kg moves along the railroad track with a constant speed of 14 m/s. What is the momentum of the car?

231000kgm/s

Explanation:

Given parameters:

Mass of train car = 16500kg

Constant speed  = 14m/s

Unknown:

Momentum of the car  = ?

Solution:

To solve this problem, we must understand that the momentum of a body is the quantity of motion a body possess.

So;

 Momentum   =  mass x velocity

 Momentum  = 16500 x 14  = 231000kgm/s

none, its a machine

iron would move it is magnetic there is a mag field around the current in the wire
