Problem 5: Centrifuges are often used to test pilots' abilities to handle varying forces resulting from complex accelerations. Given the centrifuge below, the centrifuge cab (point A) starts from rest and moves with a tangential acceleration given by at = 0.5t. a. If a pilot were to pass out when undergoing a normal acceleration of 5 g's, how long could the pilot last before passing out? b. What change would you need to make to the arm length to allow the pilot to remain conscious longer? r=8[m] A

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
