NEET Exam Model Paper 10

In simple harmonic motion, the displacement equation is, y=AsintWhere A is amplitude of the motion.
Velocity,v=

dy

dt

=Aω‌cos‌ωt
v=Aω=√1−sin2ωt
V=ω√A2−y2.........(i)
Acceleration,a=−Aω2sinωt
a=−ω2y...........(ii)
When,y=0;v=Aω=vmax
a=0=amin
When
y=A;v=0=vmin
a=−ω2A=a,max
Hence, it is clear that when v is maximum,then a is minimum (i.e., zero) or vice versa
