SUMMARY
The discussion focuses on calculating the speed of a body in simple harmonic motion (SHM) with an amplitude of 0.50 m and a period of 4π seconds. The correct formula for displacement is identified as x = A cos(2πft), where f is the frequency. By substituting the values of displacement (x = 0.30 m), amplitude (A = 0.50 m), and frequency (f = 1/(4π)), the calculated speed of the body is confirmed to be 0.20 m/s. The need to differentiate the displacement function to obtain the velocity function is also emphasized.
