Question

How much does the acceleration lead velocity in terms of radian ?

Answer 1

Hii..
Acceleration leads the velocity by phase angle π/2 radian.(simple harmonic motion)
v=Acoswt and
a= -w²Asinwt
(w=angular frequency)
Here u can see that velocity has a cos function whereas acceleration has sin function..
So acceleration leads velocity by π/2rad (90°)..

hope this helps!!
