Two water balloons of mass 0.75 kg collide and bounce off of each other without breaking. before the collision, one water balloon moved at a velocity of 3.5 m/s east, while the other moved at a velocity of 2.75 m/s west. after the collision, one balloon moves at a velocity of 1.5 m/s west. what is the velocity of the other water balloon?
