An object of mass m is pushed with the initial velocity v0 up along an inclined plane set at an angle α to the horizontal. The friction coefficient is μ.
a) Using the concepts of work and energy, determine the distance that the object will travel before it stops.
b) Find what work will the friction force perform over that distance?
