x=Acosωt,x=Acos\omega t,x=Acosωt,
v=−Aωsinωt,v=-A\omega sin\omega t,v=−Aωsinωt,
vmax=Aω,v_{max}=A\omega,vmax=Aω,
v=−vmaxsinωt,v=-v_{max}sin \omega t,v=−vmaxsinωt,
vvmax=−sinωt=12,\frac{v}{v_{max}}=-sin \omega t=\frac 12,vmaxv=−sinωt=21,
sinωt=−12, sin\omega t=-\frac 12,~~sinωt=−21, ⇒ \Rightarrow~~⇒ cosωt=32,cos\omega t=\frac{\sqrt 3}{2},cosωt=23,
x1=A32≈2.60 cm.x_1=\frac{A\sqrt3}{2}\approx2.60~\text{cm}.x1=2A3≈2.60 cm.
