A simple harmonic motion with a period of 4S and an amplitude of 2cm is made. From t / 8 to t, the distance of the particle motion is smaller than 7cm. Why How about the journey of one eighth cycle? What do you mean by 6 + (2-2sin45)?
The average speed of the first t / 8 time is smaller than the total average speed, so it will not be 1. You can find the following according to the waveform
