🤓 Based on our data, we think this question is relevant for Professor Casals' class at TAMU.

Solution: Two bags of sand are sliding on a horizontal frictionless surface. Bag A has mass 2.0 kg and bag B has mass 5.0 kg. Initially bag A is traveling east with speed vAi and bag B is traveling south with speed vBi.The two bags collide and after the collision bag A is sliding at 1.50 m/s in a direction 30.0° north of east and bag B is sliding at 2.50 m/s in a direction 37.0° south of east. What was the initial speed of each bag?
