a.) If the heavier skater reaches the edge in 10.0 s , how long does the lighter skater take to reach the edge?
Question 2. A 20 g ball of clay traveling east at 2.0m/s collides with a 30 g ball of clay traveling 30 south of west at 1.0m/s .
a.)What are the speed of the resulting 50 g blob of clay?
