Neptune should be the right answer
Answer:
initial angular momentum is given as
final angular momentum is given as
Explanation:
Angular momentum of the ball about the axis of the thin walled sphere is given as
here we know that
before it grazes the surface the speed is "v" while after grazing the surface its speed is "v/2"
So we have
initial angular momentum is given as
final angular momentum is given as
Answer:
An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes.
