A small object is released from rest at A and slides with friction down the circular path. If the coefficient of friction is 0.20, determine the velocity of the object as it passes B. Write the equations of motion in the n- and t-directions, eliminate N, and substitute v dv = at r dθ. The resulting equation is a linear nonhomogeneous differential equation of the form dy/dx + ƒ(x)y = g(x), the solution of which is well known.
