A wooden block weighing 200 g is attached to a hanger weighing 45 g with a fine thread. The block is placed on a frictionless surface and after passing thread over a smooth pulley, hanger is allowed to pull the block. Find the acceleration of the system and tension in the string.

Block A of wiehgt 100 N resta on a frictionless inclined plane of slope angle 30^@. A flexible cod attached to A passes over a frictionless pulley and is connected to block B of weight W. Find the weight W for which the system is in equilibrium.

A metal block of area 0.10 m^2 is connected to a 0.010 kg mass via a string that passes over an ideal pulley (considered massless and frictionless) as in fig.A liquid with a film thickness of 0.30 mm is placed between the block and the table.When released,the block moves ot the right with a constant speed of 00.085 m s^(-1) .Find the coefficient of viscosity of the liquid.

What is the acceleration of the block and trolley system shown in the figure, if the coefficient of kinetic friction between the trolley and the surface is 0.04?/ What is the tension in the string? (Take g = 10 ms^-2 ) Neglect the mass of the string.
