In an oscillating spring mass system, a spring is connected to a box filled with sand. As the box oscillates, sand leaks slowly out of the box vertically so that the average frequency (t) and average amplitude A(t) of the system change with time t . Which one of the following options schematically depicts these changes correctly?

Correct answer

1

Step-by-step solution

aligned & = k m & m aligned E = 1 2 kA ^2 The part of sand being removed takes away a part of energy. Total energy decreases. Energy of SHM decreases As a result Amplitude also decreases.
