Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_276

3/276 A slider \(C\) has a speed of \(3 \text{ m/s}\) as it passes point \(A\) of the guide, which lies in a horizontal plane. The coefficient of kinetic friction between the slider and the guide is \(\mu_k = 0.60\). Compute the tangential deceleration \(a_t\) of the slider just after it passes point \(A\) if (a) the slider hole and guide cross section are both circular and (b) the slider hole and guide cross section are both square. In case (b), the sides of the square are vertical and horizontal. Assume a slight clearance between the slider and the guide.
