17. Periodic Motion
Intro to Simple Harmonic Motion (Horizontal Springs)
The head of a periodic hammer moves in simple harmonic motion parallel to the x-axis at a frequency of 8.0 Hz. When t = 1.58s, the position of the head is -2.3 cm while its velocity is +20.0 cm/s. Determine the acceleration of the head at t = 1.58s.
