A particle is in simple harmonic motion with period T

QUESTION

Microsoft Word – hmwk-4-K10.rtfI know the answers, I’m just having trouble understanding the solution.A particle is in simple harmonic motion with period T. At time t = 0, it is at the equilibrium point. At which of the following times is it the largest distance from the equilibrium point?A) 0.5T B) 0.7T C) T D) 1.4T E) 1.5TA particle moves back and forth along the x axis from x = –xm to x = +xm, in simple harmonic motion with period T. At time t = 0, it is at x = +xm. When t = 1.75T:A) it is at x = 0 and is traveling toward x = +xmB) it is at x = 0 and is traveling toward x = –xmC) itisatx=+xm andisatrestD) itisbetweenx=0andx=+xm andistravelingtowardx=–xmE) itisbetweenx=0andx=–xm andistravelingtowardx=–xmA particle moves back and forth along the x axis from x = –xm to x = +xm, in simple harmonic motion with period T.
