A box of mass 4 kg is placed on a wooden plank of length `1.5`m which is lying on the ground. The plank is lifted from one end along its length so that it becomes inclined. It is noted that when the vertical height of the top end of the plank from the ground becomes `0.5`m, the box begins to slide. Find the coefficient of friction between the box and the plank.

A boy of mass m stands on one end of a wooden plank of length L and mass M. The plank is floating on water. If the boy walks from one end of the plank to the other end at a constant speed, the resulting displacement of the plank is given by :

A box is lying on an inclined plane if the box slides when the angle of inclination is 60^(@) then the coefficient of static friction of the box and the plane is?

A man of mass M stands at one end of a stationary plank of length L, lying on a smooth surface. The man walks to the other end of the plank. If the mass of the plank is M//3 , the distance that the man moves relative to the ground is

A block of mass M= 4 kg of height and breath b is placed on a rough plank of same mass M . A light inextensible string is connected to the upper end of the block and passed through a light smooth pulley as shown in figure. A mass m =1 kg is hung to the other end of the string. a. What should be the minimum value of coefficient of friction between the block and the plank so that, there is no slipping between the block and the wedge? b. Find the minimum value of b//h so that the block does not topple over the plank, friction is absent between the plank and the ground.

A plank with a box on it at one end is gradully raised about the other end. As the angle of inclination with the horizntal reaches 30^(@) , the box starts to slip and slide 4.0m down the plank in 4.0s . The coefficients of static and knitic friction between the box and the plank will be, respectively.
