Question

A bow is drawn so that it has 40 J of potential energy. When fired, the arrow will ideally have a kinetic energy that is A) less than 40 J. B) more than 40 J. C) 40 J. D) impossible to predict without additional information

Answer 1

When a bow is drawn with 40 J of potential energy, the arrow will also have 40 J of kinetic energy when fired.

Step-by-step explanation:

When a bow is drawn, it stores potential energy in its string. The potential energy is then transferred to the arrow when it is released, converting into kinetic energy. According to the law of conservation of energy, the total energy remains constant. Therefore, if the bow has 40 J of potential energy, the arrow will also have 40 J of kinetic energy when fired. Therefore, the correct answer is C) 40 J.
