Explanation:
From the question we are told that
The mass of the ball is
The radius is
The force is
The speed of the ball is
Generally the kinetic energy at the top of the circle is mathematically represented as
=>
=>
Generally the work done by the force applied on the ball from the top to the bottom is mathematically represented as
Here d is the length of a semi - circular arc which is mathematically represented as
So
Generally the kinetic energy at the bottom is mathematically represented as
=>
=>
From the law of energy conservation
=>
=>
