A 30 kg dog is running at 1 m/s and quickly comes to a stop when she sees her bone. What is the value of the force needed for her to come to a complete stop?

12000j is work done

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                                         : )
