The coefficient of stiffness of the spring is 400 N / m, the amplitude of oscillations of the pendulum

The coefficient of stiffness of the spring is 400 N / m, the amplitude of oscillations of the pendulum is 10 cm. Determine the maximum potential energy of such oscillations.

To find out the maximum potential (total) energy of oscillations of the specified pendulum, consider the formula: Ep = Епол = 0.5 * k * A ^ 2, where k is the stiffness of the spring in the specified spring pendulum (k = 400 N / m); A – amplitude (A = 10 cm = 0.1 m).

Let’s perform the calculation: Ep = 0.5 * k * A ^ 2 = 0.5 * 400 * 0.1 ^ 2 = 2 J.

Answer: The maximum potential (total) vibration energy, according to the calculation, is 2 J.
