Expert Solution

Step 1

Given:

The mass of the barbell is 13.6 kg.

The diagram is as follows:

Introduction:

The principle of work and kinetic energy states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. This definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy.
