Question

Blocks A and B are free to move within the slot. The springs are initially stretched by amount Do. When block A is at a distance D from B, its speed is vA. Block B moves after it is hit by block A. Determine a) energy loss due to the impact, b) maximum distance B moves, c) whether or not B will bounce back from the maximum position it reaches. The coefficient of static friction between A and the slot and B and the slot is ms. The coefficient of kinetic friction between A and the slot and B and the slot is mk. Given: Do= 0.3 ft, k = 20 lb/ft, L = 1.2 ft, WA = 8 lb, WB = 5 lb, D = 4 ft, vA = 12 ft/s, mk= 0.2, ms= 0.25, e = 0.8.
