*Please help this is my final* If the car has a mass of 700 kg, how many newtons of forxe were used to accelerate it 30m/s/s

21,000 N

Explanation:

You would use the formula F=ma

So you would do substitution...

F=700 kg(30 m/s/s)

F=21,000 N

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                                         : )
