A mass m is acted on by a force F,(x) = Ax' from x = 0 to x = L. (a) If m starts from rest, what is its speed at x = L? (b) Beyond x = L, F, = 0, but the mass encounters a surface with coefficient of kinetic friction 4. How far does m go before coming to rest? [Find the answer using the work-KE theorem.]
