10.a car moving at 18 m/s accelerates at -2.5 m/s² as it approaches a stop sign.
a. how long does it take the car to come to a complete stop?
b. what distance does the car travel as it is breaking?

Explanation:the time taken to stop is 7seconds

The distance traveled by the car as it breaks is 63m

hey , the answer is c

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                                         : )
