Answer:
mass of the ball will be 1 kg
Explanation:
We have given force F = 0.5 N
This force must be equal to the centripetal force for the ball to revolve in the circle
So 
Centripetal acceleration is given as 
We have to calculate the mass of the ball
We know that force is given by

So 
m = 1 kg
So mass of the ball will be 1 kg
The force applied to the spring is the weight of the object that compresses it, so it is equal to:

Because of this force, the spring compresses by

. Using Hook's law,

,
since we know the intensity of the force (the weight W) and the compression of the spring, x, we can find k, the spring constant:
Answer:
No you could not do that because if you tried even if you where to go super fast they would feel a breif second of pain before being completely riped from there body
