An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
Answer:
The vehicle with the most mass
Explanation:
Momentum is the quantity of motion in a body and it is dependent on its mass and velocity.
Momentum = m x v
m is the mass
v is the velocity
Now,
Both mass and velocity are directly proportional to momentum. Since the two bodies moves with the same velocity, the vehicle with the most mass will have the greatest momentum
