calculate the momentum for each ocean creature and then answer the question. a 500 kg dolphin swims at 4 m/s. a 700 kg sea turtle swims at 3 m/s. a 1,100 kg shark swims at 1.5 m/s. which sea creature has the most momentum?

calculate the momentum for each ocean creature and then answer the question. a 500 kg dolphin swims at 4 m/s. a 700 kg sea turtle swims at 3 m/s. a 1,100 kg shark swims at 1.5 m/s. which sea creature has the most momentum?

Answer

Explanation:

Step1: Calculate dolphin's momentum

The formula for momentum $p = mv$. For the dolphin, $m = 500$ kg and $v=4$ m/s. So $p_{dolphin}=500\times4 = 2000$ kg·m/s.

Step2: Calculate sea - turtle's momentum

For the sea - turtle, $m = 700$ kg and $v = 3$ m/s. So $p_{sea - turtle}=700\times3=2100$ kg·m/s.

Step3: Calculate shark's momentum

For the shark, $m = 1100$ kg and $v = 1.5$ m/s. So $p_{shark}=1100\times1.5 = 1650$ kg·m/s.

Step4: Compare the momenta

We have $p_{dolphin}=2000$ kg·m/s, $p_{sea - turtle}=2100$ kg·m/s, $p_{shark}=1650$ kg·m/s. Since $2100>2000>1650$, the sea - turtle has the most momentum.

Answer:

sea turtle
