Question

The displacement of a particle moving along x-axis is given by x= a sin^2wt

Answer 1

X=asin^2wt

dx/dt =2wasinwtcoswt

Velocity of particle = aw(sin2wt)

Acceleration =d^2x/dt^2 = 2w*awcos(2wt)

a=2w^2a*cos(2wt)

Answer 2

Answer:a/2

Explanation:x=2/2 a sin2wt---------(multiply and divide by 2)

x=a/2 . 2 sin2wt---------(2sin2     wtt=1-cos2wt)

x=a/2(1-cos2wt)--

x=a/2-a/2cos2wt)

so from here we can say amplitude is a/2
