A chimney is demolished by breaking its base in hope that when it falls the top of the chimney will prescribe a circle. If the chimney is broken into two segments in the air, will the top segment reach the ground first?
I have attached my professor's solution.
My professor didnt illustrate on from "both gravity and rotation". I think the rotation is just caused by gravity, and gravity only exerts its effect on rotation. Acceleration from both gravity and rotation is not that clear. Can anyone help me with it? If it can be proved by some equations, it will be helpful:) Thank you!
