A body of mass m is released from top of a rough inclined plane, if the force of friction is f,then the body Will reach the bottom with what velocity ?

Question

Piyush Kumar Behera · Answer

@Parul Rajput See in this type of problem se work energy principle,which states that, the total work done on the body=change in kinetic energy. In this question initial kinetic energy=0 Let final kinetic energy be K, length of incline=hieght x cosec where is the angle of inclination using work-energy theorem, work done by gravity+work done by friction=K-0 mg x hieght of the wedge – f x length of the inclined plane= K mg x hieght of the wedge – f x hieght x cosec =1/2mv 2 solve further to get the answer.. Hope that helps!!! please approve to encourage me thank you
