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.

Ini soal fisika di univ saya, udah saya post di website luar negri tp
ga ad yg bs jawab. mohon bantuannya
maaf kalo blom saya terjemahin
trims

I have a physic problems for university
please help me if you could solve this problem.
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
