Explanation:
How do you derive the expression for kinetic energy?
Suppose a body of mass m is moving with velocity v. It is brought to rest by applying a retarding force F. Suppose it traverses a distance s before coming to rest. Kinetic energy of body, KE = Work done by retarding force to stop it.
now...
What happens to the total energy E of a vibrating string?
the total energy is conserved, as is always zero.
please give a thanks
