15-87. The "stone" A used in the sport of curling slides over the ice track and strikes another “stone" B as shown. If each “stone" is smooth and has a weight of 47 lb, and the coefficient of restitution between the "stones" is e = 0.8, determine their speeds just after collision. Initially A has a velocity of 8 ft/s and B is at rest. Neglect friction. 3 ft 30 (vA)ı = 8 ft/s
