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

04:05

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.

in this problem, we have given a squid off mass 22.5 kilograms which shoots out water off my ass. 0.25 kilograms. It a velocity 600 centimeters per second. Andi. Because of that, it gains velocity. Let's say V we apply conservation moment. I mean this problem because there are no other external forces. The initial moment on was serious because everything was constant. And after this good shows the water out. The moment of these the total momentum is they want all this quill, which is mass. One particular glance times the velocity less the moment about the water Just 0.25 kilograms times the velocity which is minus 600 centimeters per second. Now these two are the same. The initial on the final moment. HMS must be equal. Excuse us 15 times we less minus 600. I'm set upon 250 which means we is 600 times. They don't want to fight even if they want five, which is 60 centimetres per 2nd 1 tent or the velocity of the water are 016 meters per second
