Piece a cake: a) phase constant = 1.01 rad; A = 0.038m b) X = 0.038 sin(10.pi.t + 1.01) c) a = -1.9 pi^2 m/s^2
if you want way to solve it send me japri email. Regards, Arifianto Science Depatment BINUSSCHOOLSimprug Jl.

I really appreciate your help thank you A weight which mass 1 kg, tied to a spring with spring constant (k) = 100 pi^2 N/m. The spring had a simple harmonic oscillation (in cosinus). At t(time)= 0 s, the displacement (x) is 0.032 m and the velocity is 0.24 pi m/s toward negative x axis. Find: a) Maximum displacement( Amplitude) and phase constant b)The displacement function (as a function of time x(t)) c)The acceleration when the displacement is -0.016 m Thank you very much
