The 1.9-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.

A 15-kg block moves along an inclined plane from the position “A” to position "B", which is 1 m down the incline. The spring to which the block is attached is initially stretched by 0.5 m. The coefficient of kinetic friction between the block and the surface is 0.2. A constant horizontal force of 25 N is applied to the block as shown. If the block starts from rest at position “A” and the normal force on the block is FN = 102.72 N, estimate the velocity of the block when it reaches position "B", which is 1 m down the incline. Position B Position A L = 1 m F = 25 N k, = 50 N/m H₂=0.2
