Question

An archer pulls a bow string 0.5 m. If the spring constant is 16,000 N/m, what is the energy stored in the bow string?

Answer 1

2000J

Explanation:

Given parameters:

Extension = 0.5m

Spring constant = 16000N/m

Unknown:

Energy stored in the bow string = ?

Solution:

The energy stored in a bow string is an elastic potential energy.

It can be calculated using the expression below;

     Elastic energy = $\frac{1}{2}$ K e²

Where k is the spring constant

            e is the extension

Input the parameters;

  Elastic energy = $\frac{1}{2}$ K e²

                          =$\frac{1}{2}$ x 16000 x 0.5²

                          = 2000J
