Aperson travels by car from one city to another with different constant speeds between pairs of cities. she drives for 50.0 min at 70.0 km/h, 16.0 min at 90.0 km/h, and 55.0 min at 40.0 km/h and spends 40.0 min eating lunch and buying gas. (a) determine the average speed for the trip. km/h (b) determine the distance between the initial and final cities along the route. km

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                                         : )
