Answer:

40,000kgm/s

Explanation:

Momentum = mass × velocity, the mass is always constant.

Momentum = k × velocity i.e momentum is directly proportional to velocity, when velocity is doubled the moment is also doubled.

Therefore, momentum = 20,000 kgm/s, when the velocity is doubled then the new momentum becomes 2 × 20,000 kgm/s = 40, 000kgm/s
