2.

In an intense game of Bubble Soccer, a 75 kg player running to the right at 3 m/s collides elastically (bouncy) with an 85 kg player who was running to the left at 2 m/s. After the collision, the 75 kg player bounces back at -2.3 m/s. SKETCH the collision diagram to represent before-during-after this event. Use RED for the 75 kg player and BLUE for the 85 kg player.
