Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant (and quite modest) acceleration. A train travels through a congested part of town at 7.0 m/sm/s . Once free of this area, it speeds up to 12 m/sm/s in 8.0 ss. At the edge of town, the driver again accelerates, with the same acceleration, for another 16 ss to reach a higher cruising speed. What is the final speed?

Final Speed: 26m/s

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
