Question

An object of mass 20kg is pulled up with a force of 150N on an inclined plane for a distance of 3.0 m. The plane makes an angle of 30° with the horizontal and the coefficient of kinetic friction between the object and the plane is 0.3. Draw the free body diagram and calculate the work done by each force.(Take g=10m/s×s)

Answer 1

ur whole ans is in the pic

take components of mg as directed and we get net force in upward dirn 50 N and then calculate work done by each force

ok
