A circus act involves launching a human being from a cannon resting on the floor. The human has a 50 kg mass and is launched at a speed of 12 m/s, in a direction 30° up from the horizontal. The cannon has a mass of 110 kg. (a) Considering the system as cannon + human, state why the x-component of the momentum is conserved. (b) Find the recoil speed of the cannon. (c) It would be dangerous to use explosives, so the performer is actually launched from a loaded spring inside the barrel, compressed 1.7 m from its equilibrium position. Find the spring constant needed to achieve the launch + recoil. (d) You will note that the y-component of the net momentum is NOT conserved, since the performer flies up in the air. Why is the x-component conserved but the y-component not?

“A human abortion involves the removal or ejection of a fetus or an embryo from the uterus of a woman, resulting in the death of the embryo or fetus. In humans, usually the developing organism is called an embryo during the first two months of development, and afterwards, it is called a fetus. Intentional abortions are performed by chemical or surgical means, and millions are performed worldwide every year” (Jones & Demarco, 2016). Using Kant’s ethical theory, describe a scenario...
