A spring of mass m is pulled from both sides such that is gets velocity v at both ends. What will be its kinetic energy?
Kinetic energy is defined as the form of energy that relates to the kinetics of the system. It is proportional to the square of the velocity of the body and linearly to the mass. Its SI unit is also the Joules.
Answer and Explanation:
If the spring of mass m is pulled from both sides such that both the ends get equal velocities then in sense it actually stretches as both its ends changes their position but the center of mass stays at the same position, so the velocity of the center of mass remains zero and thus the kinetic energy also remains zero and actually spring won't go anywhere.
