Find the acceleration of the block and magnitude and direction of frictional force between block A and table, if block A is pulled towards Left with a force of 50 N.

When F = 2n, the frictional force between 10 kg block 5 kg block is

Friction force acting on the block is?

Find the friction force between the blocks in the figure-2.173:

Find the direction of kinetic friction force on the block, exerted by the ground.

Find the direction of kinetic friction force on the ground, exerted by the block.

Determine the magnitude of frictional force and acceleration of the block in each of the following cases :

Find the contact force between the block and acceleration of the blocks as shown in figure.

In the three figure shown, find acceleration of block and force of friction on it in each case.

A block of mass 2kg is placed on a trolley of mass 20 kg free to move on a frictionless floor. What are the frictional force, accelerations of the block and trolley if the block is pulled by a force of 3 N ? The coefficient of friction between block and trolley is 0.25. What will be the values of all three if the block is pulled by 8 N force ? At what value of the applied force will the bodies just tend to separate ? [Hint : So long as the force applied does not produce the limiting frictional force the two will move with common acceleration. When the force applied exceeds that limiting value the block will move on the trolley with a different acceleration]

Find the force of friction acting between both the blocks shown in the figure.
