A block of mass m has initial velocity u having direction towards +x axis. The block stops after covering a distnce S causing similar extension in the spring of constant K holding it. If mu is the kinetic friction between the block and the surface on which it was moving, the distance S is given

A block of mass m has initial velocity u having direction towards +x axis. The block stops after covering a distnce S causing similar extension in the spring of constant K holding it. If mu is the kinetic friction between the block and the surface on which it was moving, the distance S is given

A block begins to move on a rough horizontal surface with an initial velocity u. If it loses of its initial kinetic energy in time t, the coefficient of kinetic friction between the block and the surface is

A block of mass m is moving on a rough horizontal surface. mu is the coefficient of kinetic friction between the block and the surface. What is the net force exerted by the surface on the block?

A block of mass m is connected to a spring of force constant k. Initially the block is at rest and the spring has natural length. A constant force F is applied hrizontally towards right. The maximum speed of the block will be (there is no friction between block and the surface)

A block of mass m is pushed momentarily along a horizontal surface with an initial velocity u. If mu_k is the coefficient of kinetic friction between the object and surface, find the time at which the block comes to rest.

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

The block of mass M in figure -4.160, initially has a velocity v_(o) to the right and its positionis much that the spring exerts no froce on it, i.e, the spring is not stretched or comkpressed. The block moves to the right a distance l before sttoping in the dotted position shown. The speing constant is k and the coefficeent of kinetic friction between block and table is mu. as the block moves the distance l, (a) what is the work done on it by the friction force ? (b) What is the work done on it by the spring force ? (c) are there other forces actionon the block, and if so what work do they do ? (d) what is the total work done on the block?
