Compare the momentum of a 6,300-kg elephant walking 0.11 m/s and a 50-kg dolphin swimming 10.4 m/s. your answer

First sum applied the Newton's second law motion: F = ma Force = mass * acceleration This motion define force as the product of mass times Acceleration (vs. Velocity). Since acceleration is the change in velocity divided by time, force = (mass*velocity) / time such that, (mass*velocity) / time=momentum/time Therefore we get mass*velocity=momentum Momentum=mass*velocity Elephant mass=6300 kg; velocity=0.11 m/s Momentum=6300*0.11 P=693 kg (m/s) Dolphin mass=50 kg; velocity=10.4 m/s Momentum=50*10.4 P=520 kg (m/s) The elephant has more momentum (P) because it is large.
