need help understanding ### Problem DescriptionA small block on a frictionless horizontal surface has a mass of 0.0200 kg. It is attached to a massless cord passing through a hole in the surface. The block is originally revolving at a distance of 0.350 m from the hole with an angular speed of 2.00 rad/s. The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.175 m. You may treat the block as a particle.### Diagram ExplanationThe figure shows a small block moving in a circular path on a horizontal surface. The block is attached to a cord that passes through a hole in the center of the circular path. The cord is being pulled downward, reducing the radius of the circle.### Questions**Part C** What is the new angular speed? *Express your answer in radians per second.*- Input box provided for the answer with units in rad/s.**Part D** Find the change in kinetic energy of the block. *Express your answer in joules.*- Input box provided for the answer with units in J.
