If a charged particle is projected on a rough horizontal surface with speed `v_(0)`. Find the value of dynamic coefficient of friction, if the kinetic energy of system is constant.

. A particle is projected up along a rough inclined plane of inclination 45^(@) with the horizontal. If the coefficient of friction is 0.5, the acceleration is

A rectangular block is kept on a rough horizontal surface and given some initial velocity. The coefficient of friction between the block and the surface is constant. The block will topple

A horizontal surface is partly smooth and partly rough. A particle is projected along the smooth part with speed u. After travelong a distance d, to rest. If mu is the coefficient of friction between particle and surface, the distance moved over the rough surface is:

A block of 10kg is pulled at a constant speed on a rough horizontal plane by a force of 20N . Calculate the coefficient of friction ?

A force of 98 N is just required to move a mass of 45 kg on a rough horizontal surface. Find the coefficient of friction and angle of friction?
