A mass attached to a spring oscillates with a period of 3.15 s.
(a) If the mass starts from rest at x = 0.044m and time t = 0, where is it at time t = 6.37 s?
(b) Is the mass moving in the positive or negative x direction at t = 6.37 s? Explain
6.37/3.15 = 2.02222 thus the value for the cos arguement is just over ...
In three lines of explanation and calculation, the problem is solved.
