In the following arrangement the pulley is assumed to be light and the strings inextensible. The acceleration of the system can be determined by considering conservation of a certaA 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 .
