Two blocks of masses m₁=8 ~kg and m₂=7 ~kg are connected by a light string passing over a light frictionless pulley. The mass m₁ is at rest on the inclined plane and mass m₂ hangs A wedge of mass M rests on a horizontal frictionless surface. A block of mass m starts sliding down the rough inclined surface of the wedge to its bottom. During the course of motiTwo blocks of masses m and 2 m are placed on a smooth horizontal surface as shown. In the first case only a force f₁ is applied from left. Later on only a force f₂ is applied from Paragraph: A wheel of a car is made up of two parts (1)the central metal rim, and (2)the rubber tyre. The width of the tyre W=16.5 ~cm and height h=10.7 ~cm .
