Calculate the momentum of a 48.5 kg passenger seated on a train that is stopped.

0kgm/s

Explanation:

Given parameters:

Mass of the passenger  = 48.5kg

Unknown:

Momentum  = ?

Solution:

The momentum of a body is the quantity of motion a body possesses. A body not in motion has no momentum.

Mathematically;

  Momentum = mass x velocity

  So;

Since the train is stopped, velocity  = 0m/s

        Momentum  = 48.5 x 0 = 0kgm/s

choosing tennis and golf balls is your inde choice.

their mass and volume are dep

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
