Question

Two planks are separated by a vertical distance of 120 m. Two bouncing balls fall and rise the full distance between the planks. Balls 1 and 2 begin falling at times t=0 sec, and t-1 sec from the top plank respectively. Both the balls begin falling at 5 m/s, and every time they hit a plank and rebound the speed is reduced by 1 m/s. Take acceleration/deceleration during falling/rising to be zero. After both the balls twice rebound from the bottom plank at what distance from the top plank do the two balls cross each other?​
