A block of mass M = 10kg is placed on a slab of mass `M_(2)= 30kg.` The slab lies on a friction less horizontal surface as shown in figure. The coefficient of static friction between the block and slab is 0.4 and that of dynamic friction is 0.15. The acceleration with which the slab will move is `(g = 1 0ms^(-1))`
