To compare the momenta of the 6,300-kg elephant and the 50-kg dolphin, we need to use the equation for momentum, which is given by:
Momentum = mass × velocity.
For the elephant:
Mass of elephant = 6,300 kg
Velocity of elephant = 0.11 m/s
To calculate the momentum of the elephant, we can plug these values into the equation:
Momentum of elephant = mass × velocity
= 6,300 kg × 0.11 m/s
= 693 kg·m/s.
Therefore, the momentum of the elephant is 693 kg·m/s.
For the dolphin:
Mass of dolphin = 50 kg
Velocity of dolphin = 10.4 m/s
Using the same equation to calculate the momentum of the dolphin:
Momentum of dolphin = mass × velocity
= 50 kg × 10.4 m/s
= 520 kg·m/s.
Therefore, the momentum of the dolphin is 520 kg·m/s.
Comparing the two momenta, we can see that the momentum of the elephant (693 kg·m/s) is greater than the momentum of the dolphin (520 kg·m/s).
