Answer:
40 000 units of momentum
Explanation:
Assuming that the mass is doubled and the velocity stays constant the new momentum will be doubled the original momentum.
The mass of a is smaller than the mass of b.
Since the sound travels from the submarine to the object AND back, it actually travelled 3625x2=7250m.
Speed of sound: 1450m/s
A vaccum unlike sound,light can travel through any matter including a great vacuum of nothing (space)
