A block \( A \) of mass \( m \) is placed over a plank \( B \) of mass \( 2 \mathrm{~m} \). Plank \( B \) is placed over a smooth horizontal surface. The coefficient of friction between \( A \) and \( B \) is \( 0.4 \). Block \( A \) is given a velocity \( v_{0} \) towards right. Find acceleration (in \( \mathrm{m} \mathrm{s}^{-2} \) ) of \( B \) relative to \( A \).https://bit.ly/YTAI_PWAP https://www.pw.live
