A simple harmonic oscillator starts from mean position at time, t = 0, moves along +x-direction are reaches the extreme point in 1s covering a distance of 20 cm
(a) The equation of its motion is `x = 0.2 "cos" (pi)/(2) t`
(b) Its maximum speed is 0.314 `ms^(-1)`
(c) Its angular frequency is `(pi)/(2) rad s^(-1)`
(d) Its maximum acceleration is `(pi^(2))/(100) ms^(-2)`
