Answer: elastic potential energy

Explanation:

The form of energy stored in the string of the bow is elastic potential energy. Elastic potential energy is the energy stored in an elastic object (such as the string of a bow) when the object is compressed/stretched by a certain amount x with respect to its natural length. The elastic potential energy stored in the object is given by

U=/frac{1}{2}kx^2U=21 kx2

where k is the spring constant of the elastic string, and x is the compression/stretching.
