A fire helicopter carries a 560-kg bucket at the end of a cable 20.6 m long as in the figure below. As the helicopter flies to a fire at a constant speed of 39.2 m/s ,the cable makes an angle of 39.6 with respect to the vertical. The bucket presents a cross-sectional area of [tex]3.96m^2[/tex] in a plane perpendicular to the air moving past it. Determine the drag coefficient, assuming that the resistive force is proportional to the square of the bucket's speed.(adsbygoogle = window.adsbygoogle || []).push({});

I've got that [tex]C_d = 2mg / (V_T)^2A\rho[/tex], but I don't know how to find the terminal velocity of the bucket to find the coefficient of drag. Can anyone help?
