Explanation:
When you dropping the swing, it increases the kinetic energy. In the middle, that is when it is at it's fullest potential. As it makes its way up, it pushes again the gravitational force, and soon, the swing will stop at the top for a VERY SHORT AND SMALL period of time. That is when it is at it's very weakest point, making the answer, indeed, A.
Answer:
L= 0.4 kgm²/s
Explanation:
The angular momentum of a hallow spinning sphere is
L = Iω
L = (0.02kgm²) × (20rad/s)
L= 0.4kgm²/s
