Physics Problem: Helicopter Carry a Payload

This is the lecture video for my online course. You can find the whole playlist here.    • Physics 01   A helicopter flies horizontally with a speed of 60 m/s. Hanging below the helicopter is a large ball with a mass of 100 kilograms and a radius of 2 meters on the end of a rope that is 3 meters long. If the sphere has a drag coefficient of C = 0.47, what angle does the rope make with the horizontal?
