Passage / Comprehension
An object of mass m is released from an initial state of rest from a spring of constant k that has been compressed a distance . After leaving the spring (at the position x = 0 when the spring is relaxed) the object travels a distance d along a horizontal track that has a coefficient of friction that varies with position as . Following the horizontal track, the object enters a quarter turn of a frictionless loop whose radius is R. Finally, after exiting the quarter turn of the loop the object travels vertically upward to a maximum height, h, (as measured from the horizontal surface).
Net work done by the friction force on block from to is :-
