Physics - W.E.P. Question with Solution | TestHub

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 $x_0$. 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 $\mu ={\mu }_0+{\mu }_1(x/d)$. 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).
