Write down the code And take a screenshot for the outputs MATLAB

A simple robotic arm can be modeled as a pendulum, like in the picture to the right. Let ? be the angular displacement of the pendulum counterclockwise from the downward position, and denote the angular velocity by w. There is damping in the pivot, and a force F is applied horizontally to the lumped mass at the end of the pendulum. The equations governing the behavior of a particular pendulum are as follows 0.4 ?-20 sin(?) + F cos(0) where the units for ? and ? are rad and rad/s, respectively, and time t is in seconds. Suppose the applied force F is such that F 0 when w20 F 2 when
