... Answer: Yes. We can use the Work-Energy Principle which says that the work done by the net force is the change in kinetic energy: Wnet = KE. In this case the net force is the force of friction. The change in KE is KEf – KEi = 0 – (1/2)mv2. CTEnergy-6. A mass m is at the end of light (massless) rod ...

... The free body diagram (FBD) is a simplified representation of an object, and the forces acting on it. It is called free because the diagram will show the object without its surroundings; i.e. the body is “free” of its environment. We will consider only the forces acting on our object of interest. Th ...
