From the side a chain is attached, as seen on the picture. Whats the mass of the chain? Heres the part I don't understand: it says that the tangent at the point where the chain attaches to the ball lies horizontally, but it doesn't show that in the picture. And the last part states that Alpha = 30° 2. Relevant equations : F = ma I guess https://gyazo.com/ee57432735c37fe601c83f440688e767 https://gyazo.com/ee57432735c37fe601c83f440688e767 3. The attempt at a solution : I have no clue. Does anyone have any hints how to go about? Also this is a year 1 college physics problem.
