Explanation / Answer

(A) Amplitude = 0.080 m

(B) Time period, T = 4 sec

w = 2pi / T = 2pi / 4

w = 1.57 rad/s

(C) m w^2 = k

k = 0.66 x 1.57^2 = 1.63 N/m


(D) at t = 1 sec ,

it is at extreme position so v = 0


(E) F = k x

at t = 1 sec, x = A

so a = F/m = k A / m = 1.63 x .080 / 0.66

a = 0.20 m/s^2
