Two cars A and B are moving with a velocity of 20 metre per second and 15 metre per second towards east and West respectively from the same place at same time. Calculate their relative velocities against each other and distance between them after 20 seconds.​

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                                         : )
