Find net work done

Classical Mechanics Level 4

A particle of mass 'm' is moved from point A to B along the track as as shown in the figure

Find the minimum work that has to be done to cause that


\(m=1 kg\)


\(AB= 2m\)

coefficient of friction = \(0.2\)

Height of first hemisphere = \(0.2m\)

Height of 2nd hemisphere= \(0.1 m\)

Height of 3rd hemisphere= \(0.01m\)
