A spring 2 is attached to the slider 1 with a mass m = 1 kg. The spring is compressed from the free state by a value of 0.1 m, after which the load is released without the initial speed. Determine the spring stiffness, if the load, having traveled a path equal to 0.1 m, acquires a speed of 1 m / s. (Answer 100)
