Two blocks with the mass of 5 kg and 10 kg respectively were overlapped and putted on a rough road. The static friction coefficient and the sliding friction coefficient between the blocks and the road are 0.6 and 0.4, respectively. The acceleration of gravity is g = 10 m/s². With a force of 105 N pushes these two blocks. (1) Find the acceleration of the two blocks. (2) Find the work done by friction force in 5 seconds. (3) Find the work done by the pushing force in 5 seconds. 5 kg F 10 kg
