Question

13. Momentum is an object’s mass times velocity. Which has more momentum? A paper airplane with a mass of 10g flying at a velocity of 4m/s, or a real airplane that is parked on a runway with a mass of 1000kg and a velocity of 0m/s

Answer 1

since the velocity of the real plane is 0, p=mv=0.  So the paper airplane actually has more momentum since it's value is not 0.
