A mass m = 2 kg, rests on a table without friction, and is attached to a spring whose return constant is k = 800 N/m. The ground is pulled, while stretching the spring 0.1 m to the right. From this initial position, the system is released. a) Calculate the work of the spring force (conservative force) to bring the system back from its initial position to its state of equilibrium. b)How fast is m when she returns to her equilibrium situation? c) What will be the maximum compression of the spring (how far will the block go to the left)? d)Calculate the work of the spring force to move the system from its initial position to the maximum compression state of the spring
