Abird sitting high in a tree is an example of an object with what type of energy? (2 points) potential energy because it has the ability to do work kinetic energy because it has the ability to do work potential energy because it is doing work kinetic energy because it is doing work 16. a cook preparing a meal for a group of people is an example of (2 points) kinetic energy because he has the ability to make a meal. potential energy because he has the ability to make a meal. kinetic energy because he is making the meal. potential energy because he is making the meal. 17. when a bow is stretched back and an arrow is shot, what type of energy conversion has occurred? (2 points) chemical to mechanical elastic to mechanical mechanical to thermal mechanical to elastic

1) the bird sitting on the tree is not moving, hence he has not kinetic energy. By the fact that the bird is high in the tree you can see that it has some potential energy (wich in this case depends on the height) and the bird has potential energy because has the ability  of doing work (lije jumping down for example)

2) the cook is moving, because he needs to do it in order to prepare the meal, then he has kinetic energy and is doing work (because he puts the energy in order to move himself) the answer is "kinetic energy because he is making the meal.

3) Ok, when you stretch the bow, it wants to return to his original shape, then you are creating elastical energy in the bow, and you are using mechanical energy to stretch the bow.  Then when the bow releases his elastical energy (also you can think that when the string is pushing the arrow, it is applying mechanical energy on the arrow), it propulsates the arrow, creating now kinetic energy into the arrow.

The correct answer is mechanical to elastic, because you need to first use mechanical energy in order to stretch the bow and create the elastic energy, and then mechanical again when the string starts to impulse the arrow.

they us to move forward and backwards
