A bow is drawn so that it has 40 J of potential energy. When the arrow is fired, its kinetic energy is ideally:
Understand the Problem
The question is asking about the relationship between potential energy stored in a bow and the kinetic energy of an arrow when it is fired. It presents a scenario where the bow has 40 J of potential energy and asks how much kinetic energy the arrow ideally has when released.
Answer
40 J
The final answer is 40 J.
Answer for screen readers
The final answer is 40 J.
More Information
In an ideal scenario with no energy losses, all the potential energy in a drawn bow converts to kinetic energy when the arrow is fired.
Tips
A common mistake is not accounting for energy loss, but in an ideal scenario, all potential energy becomes kinetic energy.
