Friction coefficients at all surfaces in the given setup is `mu_(s)`=0.5 `mu_(k)`=0.20 .Find the minimum acceleration of the block of mass `2kg` so that smaller block of mass `0.5kg` remains at rest wrt `2kg` (`g=10m/s^(2)`)

A system of two blocks is shown in figure. Friction coefficient between 5 kg and 10 kg block is mu=0.6 and between 10 kg and ground is mu=0.4 What will be the maximum value of force F applied at the lower block so that 5 kg block does not slip w.r.t. 10 kg . (g=10m//sec^(2)). The force applied at the upper block is having fixed magnitude of 80 N (both forces start to act simultaneously)

A disc of radius R=2m starts rotating wth constant angular acceleration alpha=(2rad)//s^(2) . A block of mass m=2kg is kept at a distance (R)/(2) from the centre of disc. The coeffiecient of friction between disc and block is mu_(s)=0.4,mu_(k)=0.3 . Acceleration of block when it just slips w.r.t. ground and w.r.t. disc are respectively - ( g=10ms^(-2) )

If coeffiecient of friction between the block of mass 2kg and table is 0.4 then out acceleration of the system and tension in the string. (g=10m//s^(2))

A block of mass m is placed on another block of mass M lying on a smooth horizontal surface as shown in the figure. The co-efficient of friction between the blocks is mu . Find the maximum horizontal force F (in Newton) that can be applied to the block M so that the blocks together with same acceleration? (M=3kg, m=2kg, mu=0.1, g=10m//s^(2))

Coefficient of kinetic friction between 3 kg and 2 kg block is 0.25. The horizontal table surface is smooth. Find the acceleration (in S.I. unit) of the block of mass 10 kg.

Figure shown two blocks in contact sliding down an inclined surfase of inclination 30^(@) . The friction coefficient between the block of mass 4.0kg and the incline is mu _(2) =0.30 . Find the acceleration of 2.0kg block. (g = 10m//s^(2))

The coefficient of static friction, mu_(s) between block A of mass 2 kg and the table as shown in the figure is 0.2. What would be the maximum mass value of block B so that the two blocks do not move? The string and the pulley are assumed to be smooth and massless. (g=10m//s^(2))
