A mass attached to a spring oscillates with a period of 3.26 s. If the mass starts from rest at x = 0.0410 m and time t = 0, where is it at time t = 3.27 s?
T = time period of oscillation = 3.26 s
w = angular frequency = 2pi/T = 6.28/3.26 = 1.93
A = amplitude = 0.0410
X = A Sin(wt + )
at t = 0
X = 0.0410 = A Sin
0.0410 = 0.0410 Sin
= 90
so equation becomes
X = A Sin(1.93t + /2)
at t = 3.27
X = (0.0410) Sin(1.93 (3.27) + 1.57)
X = 0.041 m
