A block \( Q \) of mass \( 2 m \) is placed on a horizontal frictionless plane. A second block of mass \( m \) is placed on it and is connected to a spring of spring constant \( K \), the two block are pulled by distance \( A \).Block \( Q \) oscillates without slipping. The work done by the friction force on block \( Q \) when the spring regains its natural length is :https://bit.ly/YTAI_PWAP https://www.pw.live
