Acar is traveling at 15 m/s. it goes down a hill where it accelerates at 3 m/s2 for 4 s. how fast is it going at the bottom of the hill?

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                                         : )
