1. What is the kinetic energy of a puma with a mass of 80 kg and a velocity of 20 m/s?

To calculate its kinetic energy, just multiply one-half of it mass by the square of its velocity. One half of 80 kg is 40 kg and the square of 8 m/s is 64 m^2/s^2. You will get an answer of 2560 joules.

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                                         : )
