The block of mass m is kept on plank of mass M. The block is given velocity `V_(0)` as shown. The coefficient of friction between the block of mass m and plank of mass M is `mu` and its value is such that block becomes stationary with respect to plank before it reaches the other end. Then:

A plank of mass M and length L is placed at rest on a smooth horizontal surface. A small block of mass m is projected with a velocity v_0 from the left end of it as shown in figure. The coefficient of friction between the block and the plank is m, and its value is such that the block becomes stationary with respect to the plank before it reaches the other end. a. Find the time and common velocity when relative sliding between the block and the plank stops. b. Find the work done by the friction force on the block during the period it slides on the plank. Is the work positive or negative? c. Calculate the work done on the plank during the same period. Is the work positive or negative? d. Also, determine the net work done by friction, Is it positive or negative?

A block of mass m is placed gently onto a long plank of mass M moving with a velocity v_(0) on a smooth horizontal floor. If friction is present between M and m :

A block of mass m is placed on the top of another block of mass M as shown in the figure. The coefficient of friction between them is mu . The maximum acceleration with which the block M may move so that m also moves along with it is

Coefficient of friction between block of mass m and fixed wedge is mu = 0.5 . For what value of (m)/(M) frictional force between block of mass m and wedge becomes zero ?

A block of mass m is gently placed over a massive plank moving horizontal over a smooth surface with velocity 10 ms^(-1) . The coefficient of friction between the block and the plank is 0.2. The distance travelled by the block till it slides on the plank is [g = 10 ms^(-2)]
