You and your friends are doing physics experiments on a frozen pond that serves as a frictionless surface. Sam(80.0 kg) slides eastward. Abbie (50.kg) slides northward. They collide. After the collision, sam slides at 6.00 m/s at 37 degrees north of east and abbie slides at 9.00 m/s south of east. What were the initial velocities of sam and abbie?
