Two ice skaters want to prove conservation of momentum. Skater A has a mass of 72 kg, and skater B has a mass of 48 kg. They are originally at rest. They hold hands and face each other. They then push off each other and move in opposite directions. Skater B moves with a velocity of 3 m/s.
What must the velocity of skater A be in the opposite direction after the push in order to prove conservation of momentum?

4.5 m/s
3.0 m/s
1.5 m/s
2.0 m/s

48 * 3 = 72 * v
So no answer?
wake up
It's 2.0m/s
