Explanation:
The force of attraction between two forces are given as
F=kQq/r²
Instantaneous velocity is the velocity at a specific instant in time. I bet you are taking Honors Physics.
It stays constant, because it's using that energy to change state
Answer:
Straight line in the direction of the tangential velocity the ball had at the moment the string broke
Explanation:
After the string breaks, the ball now disconnected from the centripetal force that was exerted via the string, continues its travel in a straight line in the direction of the tangential velocity it had at the moment the string broke.
