find the acceleration of a 1.1 kg cart pulled by a rope that goes over a pulley and has a 0.7 kg mass hanging from it. Consider the system to be frictionless and to be released from rest.

a.

explanation:

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                                         : )
