Answer:

a=-\frac{2Aw^{2}}{\pi }

Step-by-step explanation:

average acceleration is given by ∫adt÷∫dt

let equation of SHM be x=A sinwt

therefore equation of  acceleration after differentiating twice a=-Aw2sinwt

average acceleration =\int_{0}^{T/2}-Aw^{2}sinwt

\int_{0}^{T/2}dt

=\frac{-2Aw^{2}}{T}\frac{1}{w}\int_{0}^{T/2}-coswt

=\frac{2Aw}{T}[coswT/2-cos0]

a=\frac{2\pi }{w}

a=-\frac{2Aw^{2}}{\pi }
