Answer 1

wind hits on the rear face of the cylinder and the drag force acting on a rectangle with area A is $\frac{1}{2}\rho av^{2}$ and v is the relative velocity in the direction of wind (horizantal direction)

2m 60 Yılan ve velocity yo_yUT 2 POCO SHOT ON POCO F1

80 tr 3 3 3 t1 7869.216 시

so the force on the cylinder is 9869.216N
