>>>"Friction Problem"<<< 1. The problem statement, all variables and given/known data need some help... three blocks of masses 2kg ..3kg and 7kg are kept one above the other. coeff of friction between 2kg and 3 kg =0.2 coeff of friction between 3kg and 7kg=0.3 surface between 7kg block and ground=frictionless. calculate accln of each block if a force equal to 10 N is applied to the 2kg block ..3kg block and 7kg block each in three different cases. 2. Relevant equations N/A 3. The attempt at a solution i have done the work...just wanted to know the concept behind it..
