A soccer ball with a mass of 0.41 kg has a velocity of 2.5 m/s to the east. It experiences a sudden kick lasting 0.2 s, causing it to change both its speed and direction. Immediately after the kick, the ball has a velocity of 3.1 m/s to the north. What is the magnitude (in kg m/s) of the impulse that acted on the ball

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

hope that                                         : )
