Which of the following has potential but not kinetic energy? a. a roller coaster zooming down a hill b. a child riding their bike c. a bird flying from a tree d. a ball sitting on a shelf

The answer would be option D "a ball sitting on a shelf." Potential energy is the amount of energy a object has while it's at rest.. (or not moving) Kinetic energy is how much energy a object is while it's moving. So in this case it's option D because a ball sitting on a shelf isn't moving therefore it has potential energy. It's not option A because thats a example of kinetic energy since how the roller coaster is moving. It's not option B because it's kinetic energy because the bike is moving. It's also not option C because it's kinetic energy because the bird is moving.

Hope this helps!

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

i don't know that i agree with that but what's the question ?
