Block A (mA = 2 kg) is initially at rest on top of block B as shown. Atlas moves block B from rest by applying a constant horizontal force on it. Block A remains at rest on top of block B due to the frictional force f of block B on block A. How much work was done by f on block A after block A gained a kinetic energy of 10 J?
