Bulb 50 g weight is suspended on a spring with a stiffness coefficient of 49 N / m. The ball is raised to a position where the spring is not strained, and let go without jolt. Neglecting friction and the mass of the spring, to find the time and amplitude of any vibrations. Directing the x-axis is down and aligning the current x = 0 with the initial position of the ball, the ball movement to write the law.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
