Question

find a model for simple harmonic motion that has a displacement of 4.5 inches when t=0, an amplitude of 4.5 inches and a period of 8 seconds.

Answer 1

how do you define harmonic motion?

Answer 2

a point that moves on a coordinate line is said to be in simple harmonic motion if its distance d from the origin at time t is given by either d= a sin wt or d = a cos wt where a and w are real numbers such that w > 0. The motion has amplitude IaI, period 2pi/w, and frequency w/(2w)

Answer 3

all right ... what would your a=?? be then?

Answer 4

also w = 2Pi/T
