Current Attempt in Progress The 1.1-kg slider is released from rest in position A and slides without friction along the vertical-plane guide. Determine the normal force exerted by the guide on the slider (a) just before it passes point C, (b) just after it passes point C, and (c) just before it passes point E. The normal forces are positive if they point up and/or to the left, negative if they point down and/or to the right. 1.1 kg T 3.0 m A 1.3 m + B k = 34 kN/m E 30° 30%
