The mass of the wedge shown in Fig. 7.255 is M = 4 kg and that of the block is m = 1 kg. The horizontal surface beneath the wedge is smooth while the coefficient of friction between vertical surface of the wedge and block

Each of the three blocks in Fig. 7.248 has a mass of 10 kg. The coefficients of static and kinetic frictions at each surface of contact between the blocks are mu s = 0.3 and mu k = 0.2 respectively. The ground is smooth.
