A block of mass 10 kg is placed on a horizontal surface is connected by a cord passing over a frictionless pulley to a hanging block of mass 10 kg. If the coefficient of friction between the block and the surface is 0.5 and g = 10 m/s^2, then find the accleration of the system.
The given figure shows a block of mass 300 kg which is placed on a surface. If the length of the block ‘l’ is 1.5 m, breadth of the block ‘b’ is 1 m and height of the block ‘h’ is 0.5 m. What is the pressure at the bottom surface of the block?
