40 Joules. This would also mean that the ideal included zero mass or elasticity in the "string" of the bow, friction is non-existent, and it is accomplished in a vacuum.

∙ 10y agoIt doesn't matter what direction you shoot the arrow. At the instant
it leaves the string, its kinetic energy is 40 J.

When did the arrow have kinetic energy?
Right after you let go of the string and send it flying.
Is running an kinetic or potential energy?
The potential energy of the mass of the sky diver is transformed into kinetic energy during the free fall. The kinetic energy of the free fall is transformed into kinetic energy and heat of the air when the parachute is deployed.
When an arrow shot from its bow it has K.E. From where does it get K.E?
When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.
If 100J of energy are required to draw a bow what is the kinetic energy of the arrow at the moment of release?
10 Jules.
What is the simplest equation of photosynthesis?
i think that it is just:carbon dioxide + water --> oxygen + glucose(above the arrow put light energy && below the arrow put chlorophyll)the symbol equation is:6CO2 + 6H2O --> 6O2 + C6H12O6.hope this helps :)
How does the law of conservation of energy relate to a bow and?
I think you mean bow and arrow. In this case, when you pull back an arrow on a bow, you apply kinetic energy (the energy of motion) to the bow and arrow to give it potential energy (energy that can be turned into kinetic energy at a later time). Anyway, the laws of conservation of energy state that energy cannot be created or destroyed; therefore all energy in the world is only changed to other different forms. As I said above, your kinetic energy (coming from your body) applied action to the bow and arrow, making the kinetic energy change into potential energy. Of course, when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off.
What energy takes place as an arrow is shot from a bow?
The moment the arrow is released, potential energy (elastic energy in the bow) is converted into kinetic energy.
When you draw back and bend a bow you do work in bending the bow and give the arrow in the bow kinetic energy?
When you bend the bow, you are imparting kinetic energy from your pull into the bow as potential energy. When you release the string, you are imparting that potential energy into the arrow through the string.
What will be the kinetic energy of an arrow having a potential energy of 50J after its shot from a bow?
Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.
Does a flying arrow have kinetic energy?
Yes, a flying arrow has kinetic energy. Kinetic energy is the energy an object possesses due to its motion, and since the arrow is in motion, it has kinetic energy. The amount of kinetic energy depends on the mass and velocity of the arrow.
When did the arrow have kinetic energy?
Right after you let go of the string and send it flying.
Does the stiffness of the bow in a bow and arrow affect the potential energy of the bow?
Yes because the energy stored in the bow (ideally) is the force times the distance. 1 metre drawn against a force of 100 pounds (445 Newtons) gives a potential energy of 445 Joules. That energy converted totally into kinetic energy in a half-pound arrow could propel it at 44 metres/sec, or 98 mph.
How is an arrow shoot from a bow an example of the law of conservation of energy?
the reason on how this is an example is when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off - Jaylin C

What are the energy transformations when an archer pulls the string on the bow and when the archer releases the bow?
The energy in the stretched bowstring is potential energy - specifically, elastic energy. This is converted into kinetic energy, when the arrow is released.
When an arrow shot from its bow it has K.E. From where does it get K.E?
When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.
Is a pulled bow ready to shoot an arrow is it a potential or kinetic?
Potential.
