Answer to Question #182720 in Physics for ROLDAN DAVID BALUYUT

Question

When a girder in a bridge undergoes small vibrations, its displacement can be described by x= A cos 2π ft, where A is the amplitude of the vibration (that is, the maximum value of x) and f is the frequency of the vibration. Such a motion is called simple harmonic motion. Derive expressions for the velocity and acceleration for such motion.
