Important Questions on Newton's Laws of Motion (With Friction)
A box is accelerating with acceleration . A block of mass placed inside the box and is in contact with the vertical wall as shown. The friction coefficient between the block and the wall is and take . Then

on both sides and the string on the left is acted upon by a constant function force by the slit as it moves. Then

In the arrangement, as shown, the block of mass moves towards the left with velocity . Initially, the block is from a pulley on a smooth surface. Block is of mass

A triangular prism of mass with a block of mass placed on it is released from rest on a smooth inclined plane of inclination . The block does not slip on the prism. Then

Block , of mass , rests on the block , with mass , which in turn is on a horizontal tabletop (as shown in the figure). The coefficient of kinetic friction between the block and the tabletop is and the coefficient of static friction between block and block is . A light string attached to the block passes over a frictionless, massless pulley and the block is suspended from the other end of the string. What is the largest mass (in ) that block can have so that blocks and still slide together when the system is released from rest?

A block of mass is resting on a rough inclined plane of inclination as shown in the figure. The coefficient of friction between the block and the plane is . What minimum force (in newton) should be applied perpendicular to the plane on the block so that the block does not slip on the plane?

A block of mass is placed over a plank of mass Plank is placed over a smooth horizontal surface. The coefficient of friction between and is . Block is given a velocity towards the right. Find acceleration (in ) of relative to

A blocks of weight slides down an inclined plane of slope at a constant velocity, while the plank also of weight rests on top The plank is attached by a cord to the top of the plane. The coefficient of kinetic friction is the same between the surfaces and and between and Determine the value of
