BIO Momentum and the squirting squid. An interesting use of "rocket power" is that used by cephalopods such as octopi and squids. These animals take in seawater and then squirt it out at high speed. $\mathrm{A} 2.5$ -kg squid can expel 0.25 $\mathrm{kg}$ of seawater $(\mathrm{in}$ a short burst of 0.20 $\mathrm{s} )$ with a speed of 600 $\mathrm{cm} / \mathrm{s}$What is the momentum of one squirt of water?$$\begin{array}{l}{\text { A. } 1.2 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s} \text { in the direction of the squirt }} \\ {\text { B. } 1.5 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s} \text { in the direction of the squirt }} \\ {\text { C. } 12 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s} \text { in the direction of the squirt }} \\ {\text { D. } 15 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s} \text { in the direction of the squirt }}\end{array} $$

In physics, mechanical energy is the sum of the kinetic and potential energies of a system.

In physics, a conservative force is a force that is path-independent, meaning that the total work done along any path in the field is the same. In other words, the work is independent of the path taken. The only force considered in classical physics to be conservative is gravitation.

so the square shoot water off mass 0.25 kilograms it ever lost is 600 centimeters per second, which is six meters per second. So the more Wyndham off this shadow water would be simply mass times velocity. The mass of the water is 0.25 grand's so 0.5 kilograms times the velocity is six meters per second, which would be 1.5. Hey g meter per second. This would be the momentum off the water shot out.
