1. The problem statement, all variables and given/known data Find the acceleration of the blocks if a horizontal force of 10 N is applied on the 7 kg block. u1, u2 and u3 are the coefficients of friction. refer diagram. thanx in advance 2. Relevant equations 3. The attempt at a solution the force of friction between 7 kg and 3 kg is 15 N which is more than the applied force so they will move together like a single block. im confused abt the motion of the 4 kg block will it move with a different acceleration or same?
