Questions about momentum

  1. Jan 31, 2017 #1
    I need to know how to answer these two questions on momentum. The number in brackets is the number of marks.

    3a. Explain, by referring to momentum, how a jet engine can provide a forward thrust for an aircraft. (3)

    b. When the aircraft is in steady flight, its momentum is constant. Explain how the law of conservation of momentum applies even though the jet engine continues to accelerate through the air. (2)
