3.Superman is flying on the sky, suddenly approaches an airplane. It is known that this airplane has 1,000,000 kg*m/s of momentum. Superman decides to push the airplane with a force of 1,200,000 N for .09 seconds. What is the impulse that superman gives to the plane? What is the new momentum of the airplane?

Superman's delivered impulse : 108,000 kg m/s

New momentum of the airplane: 1,108,000 kg m/s

Explanation:

Recall that impulse can be estimated by multiplying the applied force times the duration of time the force was applied. Therefore, the impulse added by Superman was:

1,200,000 * 0.09 = 108,000 kg m/s

and then, the new momentum of the plane is the addition:

1000000 + 108000 = 1,108,000 kg m/s
