I think you mean the dolphin's velocity is 4 metres per second.
In which case the dolphin's momentum will be 1000 kg.m/sec
The manatee will have less momentum (700 kg.m/sec)
Linear momentum = mass times velocity.
By the way, 4 miles per second = 14,400 miles per hour.

Which has more momentum a 250 kg dolphin swimming at 6 meters per second or a 450 kg manatee swimming at 2 meters per second?
momentum = mass * velocity dolphin: 50kg*10.4m/s = 520 kg (m/s) elephant: 6300 kg * .11 m/s = 693 kg (m/s) The elephant has more momentum because of its large mass, and will be harder to stop/ change its course.
