Detailed Solution

When an arrow is released from a bow, the potential energy of the bow string gets converted to the kinetic energy of the arrow.
Mechanical Energy is the term used for the sum of the kinetic and potential energy of a body. An object's mechanical energy can result from its motion ( i.e., kinetic energy) and its stored energy of position (i.e., potential energy).
Kinetic energy:
"Kinetic energy is the energy associated with the movement of objects. Kinetic energy is directly proportional to the mass of the object (

m

) and to the square of its velocity (

v

)."

K . E = \frac{1}{2} m v^{2}

Potential energy:
"Potential energy is the energy that is stored in an object due to its position or configuration."

P . E = mgh

Where

m

is the mass,

g

is the acceleration, and

h

is the height.
When an arrow is drawn back by a bow, the work done in stretching the bowstring gets stored at potential energy in the bow. This potential energy of the bow is transformed into kinetic energy when the bowstring is released, giving kinetic energy to the arrow.
