At low speeds, the drag force exerted by...

At low speeds, the drag force exerted by air is directly proportional to speed i.e., `F_(drag)=cv`. Here, c is the constant. To determine the value of c,a small ball shaped buzzer is dropped from a high tower and the frequency recorded. It is observed that the frequency of sound decreases from an initial value of 704 Hz and becomes constant 686 Hz. taking speed of sound in air as 343 m/s and `g=10m//s^(2)`, determine the value of constant 'c' (in kg/s). the mass of buzzer is 1.8 kg.
