Question

A supersonic jet, with a mass of 21,000 kg, departs from its home airbase with a velocity of 400 m/s due east. What is the jet’s momentum?
Answer is - 21,000 x 400m/s = 84,00000 m/s

Answer 1

Answer:

Momentum  P is 840000kgm/s or 8.4 × 10^6

Explanation:

Data :

        Mass = 21000 kg

        Velocity = 400 m/s

So momentum is given as

      P = mv

      P = 21000×400

    P = 8400000 kgm/s

       P = 8.4 × 10^6
