A uniform rod of length 1m lies on the smooth part of a horizontal surface as shown. Calculate the minimum veloctiy `V_(0)` in m/s so that the rod can reach the rough surface completely. Take `g=10m//s^(2)` and coefficient of friction between the rod and the rough surface as 0.1.

A block slides with a velocity of 10 m/s on a rough horizontal surface. It comes to rest after covering a distance of 50 metre. If g is 10m//s^(2) , then the coefficient of dynamic friction between the block and the surface is

A uniform ring placed on a rough horizontal surface is given a sharp impulse as shown in the figure-5.130. As a consequence, it acquires a linear velocity of 2m/s. If coefficient of friction between the ring and the horizontal surface is 0.4 :

A uniform rod of length L and mass M has been placed on a rough horizontal surface as shown in the figure. The rod is pulled by applying a horizontal force. The coefficient of friction mu between the surface and the rod is given by mu = {(mu_(0)x, 0 le x le L),(0, x > L):} , where mu_(0) is a positive constant. The heat generated due to friction as the rod moves by a distance L is

A block slides with a velocity of 10 m/sec. on a rough horizontal surface. It comes to rest after covering of 50 m. If g is 10 m/ sec^(2) , then the coefficient of dynamic friction between the block and surface is

A uniform rod of length L and mass M has been placed on a rough horizontal surface. The horizontal force F applied on the rod is such that the rod is just in the state of rest. If the coefficient of friction varies according to the relation mu =Kx where K is a +ve constant. Then the tension at mid point of rod is?

One - fourth length of a uniform rod is placed on a rough horizontal surface and it starts rotating about the edge as soon as we release it. The rod starts slipping on the edge when it has turned through an angle theta . If the coefficient of friction between rod and surface is mu , and it satisfies the relation x tan theta=4mu , then what is the value of x? ["Take "g=10m//s^(2)]

A uniform rod of mass m and length l is at rest on smooth horizontal surface. An impulse P is applied to end B as shown. Distance travelled by the centre of the rod, while rod rotates by 90^(@)

A body of mass 10 kg lies on a rough horizontal surface. When a horizontal force of F newtons acts on it, it gets an acceleration of 5 m//s^(2) . And when the horizontal force is doubled, it gets an acceleration of 18 m//s^(2) . The coefficient of friction between the body and the horizontal surface is
