Question 2
An 80-kg man is skating northward and happens to suddenly collide with a 20-kg boy who is ice skating toward the east.
Immediately after the collision, the man and boy are seen to be moving together at 2.5 m/s in a direction 60 north of east. How fast was the boy moving just before the collision?
