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 = Im F = 25 N k, = 50 N/m 5 kg U₂ = 0.2
