    The kinetic energy of the ball when it leaves the gun is equal to 5 J.

    Explanation:

    It is given that, a child does 5.0 J of work on a spring while loading a ball into a spring-loaded toy gun. We need to find the kinetic energy of the ball when it leaves the gun when the mechanical energy of the system is conserved.

    Mechanical energy is equal to the total energy of the system. It remains conserved due to the law of conservation of mechanical energy.

    So, the kinetic energy of the ball when it leaves the gun is equal to 5 J. Hence, this is the required solution.
