A car was going at 20m/s along a straight highway. The driver slams on the break to avoid hitting a deer. The car had a negative acceleration of -2m/s^2 How much time did it take the car to stop

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                                         : )
