D' Alembert's Principle| Problem Solving #8| Engineering Mechanics

Hey Guys!! This is Zainali and I am back with a new tutorial in which we would be solving a problem using D' Alembert's principle. PROBLEM STATEMENT: A 20kg body is moving to right with a velocity of 10m/s on a horizontal ground with coefficient of friction as 0.5. A variable force P= 150+2t is applied to the left, where t is in sec. What is the velocity of the body after 5 sec? At what time will the velocity of mass be zero?
