(a) V=dy/dt=awcoswt

V_max=aw=30

Acceleration A= $\frac{d{x}^2}{d{t}^2}=-a{w}^{2}sinwt$

A=w²a=60

So after solving w =2rad/s

2 $\frac{\pi }{T}=2rad/s$

T= $\pi sec$

(c) x=acos (  $\alpha t$ )², so it is SHM motion.

X (t+T)=acos [ $\alpha (t+T)$ ]²

= acos [ $\alpha t^2+\alpha T^2+2\alpha tT$ ]

So it is not periodic.

So it is oscillatory but not periodic
