a full draw is the maximum distance that an archer can pull an arrow. Using the recurve bow shown below, a particular archer requires an average force of 130N to pull a full draw of 70.0cm. (when the arrow is relaxed in the bow, there is a distance of 30.0cm btween the arrow touching the back string and the middle of the arcc. When the arrow is stretched, the distance is now increased by 700.0cm to a total of 100.0 cm).
1. How much potential energy is stored in the bow?
2. If the arrow has a mass of 18.5 g(0.0186kg), what is the maximum speed that the arrow could leave the bow with(assuming all potential energy is transformed into the kinetic energy of the arrow)?
3. If the arrow only leaves the bow with a speed of 54m/s, how much energy was lost to heat?
