A cubical block of side `a` and density `rho` slides over a fixed inclined plane with constant velocity `v`. There is a thin film of viscous fluid of thickness `t` between the plane and the block. Then the coefficient of viscosity of the thin film will be: (Acceleration due to gravity is g)

Two blocks of equal mass are released on two smooth sides of a duble inclined plane with a fixed base as shown in the figure. If each angle of inclination is 45^(@) , the acceleration of the centre of mass of the system of the two blocks is (Acceleration due to gravity =10" ms"^(-2) )

A block slides down an inclined plane of slope angle 0 with constant velocity .It is then projected up the same plane with an initial velocity v_0 .How far up the incline will it move?

A block is pushed up a rough inclined plane of 45^(@) with a velocity u. The block rises up and then comes down sliding to have a velocity u/2 at the bottom. The coefficient of sliding friction between block and the plane is

A block sliding down on a rough 45^(@) inclined planes has half the velocity it would have been, the inclined plane is smooth. The coefficient of sliding friction between the the block and the inclined plane is

A rough inclined plane BCE of height (25/6)m is kept on a rectangular wooden black ABCD of height 10 m , as shown in the figure. A small block is allowed to slide down from the top E of the inclined plane. The coefficient of kinetic friction between the block and the inclined plane is 1/8 and the angle of inclination of the inclined plane is sin^-1 (0.6) . IF the small block finally reaches the ground at a point F, then DF will (Acceleration due to gravity, g=10 ms^-2 )
