Question 1103942: Assume that the simple harmonic motion of a spring is described by the equation where is in cm and is in seconds. When during the time, 0 to 8 seconds, is the spring passing through the origin? Answer by ikleyn(52787) (Show Source):
S = 0 every time when = , , , , which corresponds to values of t = 1, 3, 5, 7 seconds.
Answer. S = 0 at t = 1 second, 3 seconds, 5 seconds and 7 seconds in the interval from 0 to 8 seconds.
